GENERAL
This installation instruction contains basic unit installation
information, including installation of thermostats and remote
temperature sensors.

For additional information and service instructions, refer to
the Controls and Troubleshooting literature.
A factory-installed optional integral economizer and highcapacity power exhaust is available on size 075-100 units.
A factory-installed optional return fan is available on size
075-100 units.
The staged gas control (SGC) option adds the capability to
control the rooftop unit’s gas heating system to a specified
supply-air temperature set point for purposes of tempering a
cool mixed-air condition.

SAFETY CONSIDERATIONS
Installation and servicing of air-conditioning equipment can
be hazardous due to system pressure and electrical components. Only trained and qualified service personnel should
install, repair, or service air-conditioning equipment.
Untrained personnel can perform basic maintenance functions of cleaning coils and filters and replacing filters. All
other operations should be performed by trained service personnel. When working on air-conditioning equipment, observe
precautions in the literature, tags and labels attached to the unit,
and other safety precautions that may apply.
Follow all safety codes, including ANSI (American National Standards Institute) Z223.1. Wear safety glasses and work
gloves. Use quenching cloth for unbrazing operations. Have
fire extinguisher available for all brazing operations.

WARNING
Before performing service or maintenance operations on
unit, turn off main power switch to unit. Electrical shock
could cause personal injury.

FOR YOUR SAFETY
WHAT TO DO IF YOU SMELL GAS
Do not try to light any appliance. Do not touch any electrical switch; do not use any phone in your building. Immediately call your gas supplier from a neighbor’s phone.
Follow the gas supplier’s instructions. If you cannot reach
your gas supplier, call the fire department.

FOR YOUR SAFETY
Do not store or use gasoline or other flammable vapors and
liquids in the vicinity of this or any other appliance.

WARNING
Improper installation, adjustment, alteration, service, or
maintenance can cause injury or property damage. Refer to
this manual. For assistance or additional information, consult a qualified installer, service agency, or the gas supplier.

Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

sufficient height to allow for condensate trap of 4 in. on sizes
030-070 or 7 in. on sizes 075-100.

CAUTION
Disconnect gas piping from units when leak testing at pressures greater than 0.5 psig. Pressures greater than 0.5 psig
will cause gas valve damage resulting in a hazardous
condition. If gas valve is subjected to pressure greater than
0.5 psig, it must be replaced. When pressure testing fieldsupplied gas piping at pressures of 0.5 psig or less, the unit
connected to such piping must be isolated by manually
closing the gas valve.

Step 5 — Install Curb Gasketing
SIZE 030-060 UNITS — After ductwork has been connected
to the roof curb, attach adhesive-backed gasketing on all end
rails, cross rails, and duct rails. Be sure all joints and corners of
gasket are square and flush to prevent possible water leaks.
Follow all applicable building codes.
SIZE 070-100 UNITS — After ductwork has been connected
to the roof curb, apply gasket material (1/2-in. thick x 11/2-in.
wide neoprene) where indicated.
Single-Thickness Gasketing (See Fig. 6-8 for Item Numbers) — Apply gasketing in the following places:
1. Along both side rails (1) — 2 places, full length
2. Along return air end rail (2) — 1 place
3. Around return air internal duct flange (3) — 1 or 2 places
4. Around supply air internal duct flanges (4) — 3 places
Double-Thickness Gasketing (See Fig. 6 and 8 and Detail
A-A) — Locate a line 93/4-in. from the supply air end of the
accessory curb. Apply a double-thickness of gasket material
along line per detail A-A.
NOTE: Do not apply gasket material along the outside edge of
the curb (area “X”). This pan area of the curb extends out
beneath the end of the unit’s air handler section; applying gasket here develops a potential water trap area on top of the curb.
Condenser Section Roof Curb (See Fig. 7) — Apply singlethickness gasket along both side rails (5).

INSTALLATION
Step 1 — Perform Jobsite Survey — Complete
the following checks before installation.
1. Consult local building codes and the NEC (National
Electrical Code) (ANSI/NFPA [American National Standards Institute/National Fire Protection Association] 70)
for special installation requirements.
2. Determine unit location (from project plans) or select unit
location.
3. Check for possible overhead obstructions which may interfere with unit lifting or rigging.
CAUTION
Do not lift unit with forklift truck. Move unit with overhead rigging only.

Step 2 — Place Unit — Inspect unit for transportation

Step 6 — Install Field-Fabricated Ductwork

damage. File claim with transportation agency.
Provide clearance around and above unit for airflow, safety,
and service access. Do not restrict top (area above condenser
fans) in any way. Allow at least 6 ft on all sides for rated performance, code compliance, and service. On units equipped with
power exhaust option, high velocity air is exhausted out the
hood. Unit should be positioned with at least 10 ft clearance between the exhaust hood and any obstruction.
Check unit dimensional drawings for unit arrangement and
minimum performance and service clearances.
Do not install unit in an indoor location. Do not locate air inlets near exhaust vents or other sources of contaminated air.
Although unit is weatherproof, guard against water from
higher level runoff and overhangs.
Level by using unit frame as a reference. Physical data is
shown in Tables 1A-9.

WARNING
For vertical supply and return units, tools or parts could
drop into ductwork and cause an injury. Install a 90-degree
elbow in the supply and return ductwork between the unit
and the conditioned space. If a 90-degree elbow cannot be
installed, then a grille of sufficient strength and density
should be installed to prevent objects from falling into the
conditioned space. Failure to follow these instructions
could result in personal injury or property damage due to
falling objects.
The 48P2,P3 units are designed for vertical supply/return
only. Field-fabricated ductwork must be attached to the roof
curb, or to the support steel, prior to the final rigging and installation of the unit. Supply and return duct dimensions are shown
in Fig. 1-3.
To attach ductwork to roof curb, insert duct approximately 10
to 11 in. up into roof curb. Connect ductwork to 14-gage roof
curb material with sheet metal screws driven from inside the duct.
Secure all ducts to the building structure, using flexible duct
connectors between roof curbs and ducts as required. Ducts
passing through an unconditioned space must be insulated and
covered with a vapor barrier. Outlet grilles must not lie directly
below unit discharge.
Design supply duct strong enough to handle expected static
pressures.

Step 3 — Roof Mount Unit — Check building codes
for weight distribution requirements. Unit weight is shown in
Tables 1A-1C and 5. Unit may be mounted on class A, B, or C
roofing material.
ROOF CURB — Assemble and install roof curb as described
in instructions shipped with the accessory. Accessory roof curb
and information required to field fabricate a roof curb is shown
in Fig. 1-5. Install insulation, cant strips, roofing and counter
flashing as required. For unit condensate drain to function
properly, curb must be level or within tolerances shown in
Fig. 1-5.
STEEL BEAMS — If roof curb is not used, support unit with
steel beams along its entire length and then support steel as required. As a minimum, unit must be supported across its width
at each lifting lug location.

Step 7 — Rig Unit — Do not drop unit; keep upright.
Use spreader bars over unit to prevent sling or cable damage.
Sheets of plywood placed along the condenser coils will provide additional protection. All lifting lugs MUST be used when
lifting unit. Level by using unit frame as a reference. See Fig. 9
and 10 for information. Unit and accessory weights are shown
in Tables 1A-1C and 5. Weight distribution and center of gravity can be found in Fig. 11.

Step 4 — Slab Mount Unit — Provide a level concrete slab that extends beyond unit cabinet at least 6 inches.
Make a slab 8 in. thick with 4 in. above grade. Use gravel
apron in front of condenser coil air inlet to prevent grass and
foliage from obstructing airflow. Ensure that slab is of

four 0.20-in. engagement holes. Install a drain coupling assembly using screws provided at each secondary drain hole location. See Fig. 26. Do not attach any drain coupling assemblies
in the condenser section base rail.
Using field-supplied fittings and pipe sections, assemble Utraps at each secondary drain fitting. See Fig. 27. Provide a
minimum size of ½-in. pipe for secondary drains. Use a trap at
least 4-in. deep for size 030-070 units and 7-in. deep for size
075-100 units. Apply a bead of RTV or similar sealant around
the drain assemblies.
Consult local plumbing codes for direction on joining multiple drain lines. Total size of any combined line does not need
to exceed nominal 2-in. size of primary drain connection.
Fill the U-traps at the secondary drain locations prior to unit
start-up. Also check the U-traps before each cooling season to
ensure the traps are filled and functioning properly.
SECONDARY DRAINS (Units Installed on Steel Beam or
Slab) — There are two secondary drain connections required
on each side of the unit. There are secondary drains on the bottom of the base rail on each side of the unit in the filter section
and on each side of the unit in the supply fan section. There are
labels marking each location on the unit base rail. See Fig. 1221. Drain holes will need to be drilled in these locations at the
side of the base rail. The existing secondary drain holes in the
bottom of the base rail must be sealed. Prior to final positioning
of the unit, apply a bead of RTV or similar sealant around each
secondary drain hole in the bottom of the unit base rail. See
Fig. 27. Install the metal seal plates then position the unit into
final location.

Step 8 — Connect Condensate Drain — There

are a total of five drain connections required on each unit: one
primary drain (on right-hand side of the unit) and four secondary drains (two on each side of unit).
PRIMARY DRAIN — The primary drain is a 2-in. FPT pipe
connection located on the right-hand side of the unit looking at
the unit from the return air end. See Fig. 12-21. Fig. 22 shows
the additional length of units with an extended chassis.
With field-supplied fittings and pipe sections, plumb the primary condensate drain to the 2-in. FPT connector on the base
rail. Use a trap height of at least 4-in. for size 030-070 units
and 7-in. for size 075-100 units. See Fig. 23 and 24. Install with
a height dimension of at least 2-in. from the top of the exit pipe
from the trap section to the bottom of the connector. Apply a
bead of RTV or similar sealant around the pipe joint at the connector in the base rail.
SECONDARY
DRAINS
(Units
Installed
on
Curb) — There are two secondary drain connections on each
side of the unit. See Fig. 25. There are secondary drains on
each side of the unit in the filter section and on each side of the
unit in the supply fan section. There are labels marking each location on the unit base rail. See Fig. 12-21.
Locate the four 11/4-in. drain coupling assemblies and
mounting screws (shipped in a bag taped to the basepan in the
supply fan section, located behind the access panel marked
FAN SECTION). The drain couplings are a 10-gage plate with
a 11/4 in. half coupling welded to the plate.
At each secondary drain hole location, there is a 13/8-in.
hole pre-drilled in the bottom of the base rail, surrounded by

4. Using field-supplied fittings and pipe sections, assemble
U-traps at each secondary drain fitting. See Fig. 24. Provide minimum size of ½-in. pipe for secondary drains.
Use a trap at least 4-in. deep for size 030-070 units and
7-in. deep for size 075-100 units.
5. Apply a bead of RTV or similar sealant around the drain
assemblies.
Consult local plumbing codes for direction on joining multiple drain lines. Total size of any combined line does not need to
exceed nominal 2-in. size of primary drain connection.
Fill the U-traps at the secondary drain locations prior to unit
start-up. Also check the U-traps before each cooling season to
ensure the traps are filled and functioning properly.

Locate the four 11/4-in. drain coupling assemblies and
mounting screws (shipped in a bag taped to the basepan in the
supply fan section, located behind the access panel marked
FAN SECTION). The drain couplings are a 10-gage plate with
a 11/4 in. half coupling welded to the plate.
After final positioning of the unit, perform the following
procedure:
1. At each of the four secondary drain locations (marked
with labels on the unit base rail), position the drain coupling assembly in the side of the base rail. Mark the
screw holes and the drain hole locations on the base rail.
2. Drill holes for drain outlet (use 13/8-in. hole saw) and for
the mounting screws (use 3/16-in. drill bit).
3. Install a drain coupling assembly using screws provided
at each secondary drain hole location.

drives) generate, use, and can radiate radio frequency
energy. If units are not installed and used in accordance
with these instructions, they may cause radio interference. They have been tested and found to comply with
limits of a Class A computing device as defined by FCC
(Federal Communications Commission) regulations,
Subpart J of Part 15, which are designed to provide reasonable protection against such interference when operated in a commercial environment.

= 457
Determine maximum deviation from average voltage:
(AB) 457 – 452 = 5 v
(BC) 464 – 457 = 7 v
(AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
Determine percent voltage imbalance:
% Voltage Imbalance = 100 x

POWER WIRING — Units are factory wired for the voltage
shown on the unit nameplate. The main terminal block is suitable for use with aluminum or copper wires. Maximum wire
size varies according to disconnect size.
Units without Factory-Installed Disconnect — When installing units, provide a disconnect per NEC (National Electrical
Code) of adequate size (MOCP [maximum overcurrent protection] of unit is on the informative plate). All field wiring must
comply with NEC and all local codes. Size wire based on
MCA (minimum circuit amps) on the unit informative plate.
See Fig. 41 for power wiring connections to the unit power

457

= 1.53%
This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
IMPORTANT: If the supply voltage phase imbalance is
more than 2%, contact local utility immediately.
Unit failure as a result of operation on improper line voltage
or excessive phase imbalance constitutes abuse and may cause
damage to electrical components.

area near the entrance lobby (or other appropriate and sensitive
location) so that location is controlled as closely to design pressures as possible.
These units use a pressure transducer for sensing building
pressure. The BP transducer is located in the unit auxiliary control box. See Fig. 44 and 45 for auxiliary control box location.
See Fig. 46 and 47 for auxiliary control box details. Use a nominal 1/4-in. plastic tubing.
For instructions on adjusting BP control set points, refer to
the Controls and Troubleshooting book.
RETURN FAN POWER EXHAUST — The tubing for the
building pressure (BP) control (achieved via the return power
exhaust option) should sample building pressure in the area
near the entrance lobby (or other appropriate and sensitive location) so that location is controlled as closely to design pressures as possible.
The units use a pressure transducer for sensing building
pressure. The BP transducer is located in the unit auxiliary control box. See Fig. 45 for auxiliary control box location. See
Fig. 48 for auxiliary control box details. Use a nominal 1/4 in.
plastic tubing.
For instructions on adjusting BP control set points, refer to
the Controls and Troubleshooting book.

Step 13 — Connect Air Pressure Tubing — Before options such as the variable frequency drive (VFD) and/or
modulating power exhaust can operate properly, the pneumatic
tubing for pressure sensing must be installed. Use fire-retardant
plenum tubing (field-supplied). All control devices use 1/4-in.
tubing. Tubing must be run from the appropriate sensing location (in the duct or in the building space) to the control device
location in the unit.
VARIABLE FREQUENCY DRIVE — The tubing for the
duct pressure (DP) control option should sample supply duct
pressure approximately 2/3 of the way out from the unit in the
main trunk duct, at a location where a constant duct pressure is
desired.
On these units, the duct pressure is sensed by a pressure
transducer. The pressure transducer output is directed to the unit
control module. On all sizes, the DP transducer is located in the
unit auxiliary control box. See Fig. 44 and 45 for auxiliary
control box location. See Fig. 46-48 for auxiliary control box
details. Use a nominal 1/4-in. plastic tubing.
Refer to appropriate base unit Controls and Troubleshooting
book for instructions on adjusting set points for duct pressure
controls.
MODULATING POWER EXHAUST — The tubing for the
building pressure (BP) control (achieved via the modulating
power exhaust option) should sample building pressure in the

SGC — Staged Gas Controller

On size 040-060 units, in areas with prevailing winds of
more than 5 mph and where temperatures drop below 32 F,
wind baffles must be field fabricated to ensure proper cooling
cycle operation at low-ambient temperatures with Motormaster
V controls. Wind baffles are not needed on size 030, 035, and
070-100 units. See Fig. 70 for baffle details. Use 20-gage galvanized sheet metal, or similar corrosion-resistant material for the
baffles. Use field-supplied screws to attach baffles to unit.
Screws should be 1/4-in. diameter or larger. Screws should not
be more than 1/2-inch in length. Drill required screw holes for
mounting baffles.

Step 20 — Install Optional Motormaster® V
Control — The Motormaster V control is a motor speed

control device which adjusts condenser fan motor speed in response to varying liquid refrigerant pressure. A properly applied
Motormaster V control extends the operating range of air-conditioning systems and permits operation at lower outdoor ambient
temperatures.
The optional Motormaster V controls are factory-installed.
Field-fabricated and installed wind baffles are also required for
units in areas with prevailing winds of more than 5 mph and
where temperatures drop below 32 F. The Motormaster V control permits operation of the unit to an ambient temperature of
–20 F. The control regulates the speed of one or two 3-phase fan
motors depending on unit size. Replacement of the fan motor on
most units is not necessary.
INSTALL FIELD-FABRICATED WIND BAFFLES

CAUTION
To avoid damage to refrigerant coils, electrical components, and wiring use extreme care when drilling screw
holes and screwing in fasteners.

WARNING
To avoid the possibility of electrical shock, open all disconnects before installing or servicing this accessory.

SENSORS — Sensors should be wired using single twisted
pairs of 20 AWG (American Wire Gage) conductor cable rated
for the application, except for the T-56 accessory sensor which
requires 3-conductor cable.
HUMIDITY CONTROL AND HOT WATER AND
STEAM VALVES — These devices require 20 AWG twisted
pair conductor cables rated for the application for the 4 to
20 mA signal.
SPACE TEMPERATURE SENSOR (T-55) — The space temperature sensor (P/N 33ZCT55SPT), if used, is wired to terminals in the unit main control box. To connect the space temperature sensor, see Fig. 72.
SPACE TEMPERATURE SENSOR (T-56) — The space temperature sensor (P/N 33ZCT56SPT), if used, is wired to terminals in the unit main control box. To connect the space temperature sensor, see Fig. 72.
COMMUNICATING SPACE TEMPERATURE SENSOR
(T-58) — The communicating space temperature sensor (P/N
33ZCT58SPT) is wired to the Carrier Comfort Network®
(CCN) connections on TB202.
SPACE TEMPERATURE AVERAGING — Applications that
require averaging using multiple space temperature sensors can
be satisfied using either 4 or 9 sensors as shown in Fig. 73.
NOTE: Only Carrier sensors may be used for standard T-55
space averaging. Sensors must be used in multiples of 1, 4, and
9 only, with total sensors wiring not to exceed 1000 ft.
NOTE: Do not use T-56 sensors for space temperature averaging because the 5-degree offset function will not work in a
multiple sensor application.
HEAT INTERLOCK RELAY (VAV Units Only — Not Necessary for Digital Air Volume Applications) — Variable air volume (VAV) units using morning warm-up and/or occupied
heating require that room terminals be controlled to a position
that provides the minimum required heating cfm or greater
when the unit goes into Heating mode. The HIR (heat interlock
relay) function is provided for this control. When the unit goes
into Heating mode, the HIR is energized to provide switch closure or opening (depending on how the field-supplied power
source is set up) to open the room terminals. The field connections for the HIR are at TB201 terminals 9 and 10. See Fig. 74.

Fig. 84 — CCN Connections

Carrier Comfort Network® (CCN) Interface —

IMPORTANT: When connecting the CCN communication bus to a system element, use a color coding system for
the entire network to simplify installation and checkout.

The 48P Series units can be connected to the CCN system if
desired. The communication bus wiring is supplied and
installed in the field. It consists of shielded, 3-conductor cable
with shield wire.
The system elements are connected to the communication
bus in a daisy chain arrangement. The positive pin of each
system element communication connector must be wired to the
positive pins of the system element on either side of it, the
negative pins must be wired to the negative pins, and the signal
pins must be wired to common pins. Wiring connections for
the CCN system should be made at the terminal block using the
screw terminals. The board also contains an RJ14 CCN plug
that can be used to connect a field service computer. There is
also another RJ14 LEN (Local Equipment Network) connection that is used to download software or connect a Navigator™ device.
NOTE: Conductors and drain wire must be 20 AWG minimum
stranded, tinned copper. Individual conductors must be insulated with PVC, PVC/nylon, vinyl, Teflon, or polyethylene. An
aluminum/polyester 100% foil shield and an outer jacket of
PVC, PVC/nylon, chrome vinyl, or Teflon with a minimum
operating temperature range of –4 to 140 F (–20 C to 60 C) is
required. See Table 28 for cables that meet the requirements.

The following color code is recommended:
SIGNAL
TYPE
+
COMMON
–

COMM1 PLUG
PIN NO.
1
2
3

NOTE: If a cable with a different color scheme is selected, a
similar color code should be adopted for the entire network.
At each system element, the shields of its communication
bus cables must be tied together. If the communication bus is
entirely within one building, the resulting continuous field
must be connected to a ground at one point only. If the communication bus cable exits from one building and enters another,
the shields must be connected to grounds at the lightning
suppressor in each building where the cable enters or exits the
building (one point per building only).
To connect the unit to the network (Fig. 84):
1. Turn off power to the control box.
2. Cut the CCN wire and strip the ends of the red (+), white
(common) and black (–) conductors. (If a different network color scheme is used, substitute appropriate colors.)
3. Wire the CCN to the screw terminals on the COMM
board as follows (Fig. 84):
a. Secure the red (+) wire to CCN screw terminal +
on the COMM board.
b. Secure the white (common) wire to CCN screw
terminal C on the COMM board.

using the BACview keypad/display unit, press and hold
the “FN” key then press the “.” Key.
To install a BT485 terminator, push the BT485 on to the
BT485 connector located near the BACnet connector.
NOTE: The BT485 terminator has no polarity associated with
it.
To order a BT485 terminator, consult Commercial Products
i-Vu® Open Control System Master Prices.
MS/TP WIRING RECOMMENDATIONS — Recommendations are shown in Tables 29 and 30. The wire jacket and UL
temperature rating specifications list two acceptable alternatives. The Halar specification has a higher temperature rating
and a tougher outer jacket than the SmokeGard specification,
and it is appropriate for use in applications where the user is
concerned about abrasion. The Halar jacket is also less likely to
crack in extremely low temperatures.
NOTE: Use the specified type of wire and cable for maximum
signal integrity.

c. Secure the black (–) wire to CCN screw terminal –
on the COMM board.
d. Secure shield wire to CCN screw terminal
SHIELD on the COMM board.
IMPORTANT: A shorted CCN bus cable will prevent
some routines from running and may prevent unit from
starting. If abnormal conditions occur, unplug the connector. If conditions return to normal, check CCN connector,
and run new cable if necessary. A short in one section of
the bus can cause problems with all system elements on
the bus.

Optional UPC Open Installation
WIRING THE UPC OPEN TO THE MS/TP NETWORK — The UPC Open controller communicates using
BACnet on an MS/TP network segment communications at
9600 bps, 19.2 kbps, 38.4 kbps, or 76.8 kbps.
Wire the controllers on an MS/TP network segment in a daisy-chain configuration. Wire specifications for the cable are
22 AWG (American Wire Gage) or 24 AWG, low-capacitance,
twisted, stranded, shielded copper wire. The maximum length
is 2000 ft.
Install a BT485 terminator on the first and last controller on
a network segment to add bias and prevent signal distortions
due to echoing. See Fig. 85-87.
To wire the UPC Open controller to the BAS network:
1. Pull the screw terminal connector from the controller's
BAS Port.
2. Check the communications wiring for shorts and
grounds.
3. Connect the communications wiring to the BAS port’s
screw terminals labeled Net +, Net -, and Shield.
NOTE: Use the same polarity throughout the network
segment.
4. Insert the power screw terminal connector into the UPC
Open controller's power terminals if they are not currently connected.
5. Verify communication with the network by viewing a
module status report. To perform a module status report

Smoke Control Modes — Rooftop units can be used

for aid in building smoke control in the event of a building fire.
The available functions include: Fire Shutdown, Pressurization, Evacuation, and Smoke Purge. These functions are
enhanced when multiple rooftop units are used to zone a building. See Table 31 and Fig. 82 and 83.
FIRE SHUTDOWN — Fire Shutdown mode terminates all
unit operation (cooling, heating, supply fan, and power
exhaust). This mode prevents recirculation of contaminated air
back into the space. The mode will not allow admission into
the space of unsuitable outside air. See Fig. 82 for wiring.
PRESSURIZATION — Pressurization mode is intended to
keep smoke out of a zone. The factory-installed optional economizer is required for this function. Pressurization is accomplished by the following:
• opening the economizer (option)
• running the supply fan (optional inlet guide vanes open
or optional VFD at normal duct static pressure set point)
• closing the power exhaust dampers (if installed as option
or accessory)
• shutting off the power exhaust fans (if installed as option
or accessory)

accessory power exhaust is required for this function. Evacuation is accomplished by the following:
• turning the supply fan off
• opening the economizer (option required)
• running the exhaust fans (option or accessory required)
• opening the exhaust dampers.
See Fig. 82 for wiring.

This allows the space to be overpressurized relative to adjacent
zones and prevents or slows entry of smoke into this space
from adjacent zones. See Fig. 82 for wiring.
