NOTES (pages 2 - 7)
1. Minimum circuit ampacity (MCA) is based on 125% of the rated load amps for the largest motor plus 100% of the rated load amps for all
other loads included in the circuit, per N.E.C. Article 430-24. If a Factory Mounted Control Transformer is provided, add the following to
the system #2 MCA values in the YCAS Tables: -17, add 10 amps; -28, add 9 amps; -40, add 5 amps; -46, add 4 amps; -58, add 3 amps.
2. The recommendation disconnect switch is based on a minimum of 115% of the summation rated load amps of all the loads included in the
circuit, per N.E.C. 440 - 12A1.
3. Minimum fuse size is based on 150% of the largest motor RLA plus 100% of the remaining RLAs (U.L. Standard 1995, Section 36.1).
Minimum fuse rating = (1.5 x largest compressor RLA) + other compressor RLAs + (# fans x each fan motor FLA).
4. Maximum dual element fuse size is based on 225% maximum plus 100% of the rated load amps for all other loads included in the circuit,
per N.E.C. 440-22. Maximum fuse rating = (2.25 x largest compressor RLA) + other compressor RLAs + (# fans x each fan motor FLA).
5. Minimum circuit breaker is 150% maximum plus 100% of rated load amps included in the circuit, per circuit per U.L. 1995 Fig. 36.2.
Minimum circuit breaker rating = (1.5 x largest compressor RLA) + other compressor RLAs + (# fans x each fan motor FLA).
6. Maximum circuit breaker is based on 225% maximum plus 100% of the rated load amps for all loads included in the circuit, per circuit, per
U.L. 1995 Fig. 36.2. Maximum circuit breaker rating = (2.25 x largest compressor RLA) + other compressor RLAs + ( # fans x each fan
motor FLA).
7. The Incoming Wire Range is the minimum and maximum wire size that can be accommodated by unit wiring lugs. The (1), (2), or (3)
indicate the number of termination points or lugs which are available per phase. Actual wire size and number of wires per phase must be
determined based on ampacity and job requirements using N.E.C. wire sizing information. The above recommendations are based on the
National Electric Code and using copper connectors only. Field wiring must also comply with local codes.
8. A ground lug is provided for each compressor system to accommodate field grounding conductor per N.E.C. Article 250-54. A control
circuit grounding lug is also supplied. Incoming ground wire range is #6 - 350 MCM.
9. The field supplied disconnect is a Disconnecting Means as defined in N.E.C. 100.B, and is intended for isolating the unit from the
available power supply to perform maintenance and troubleshooting. This disconnect is not intended to be a Load Break Device.
10. Units equipped with Star-Delta compressor motor start must also include Factory provided circuit breakers in each motor control center.
11. The wiring recommendations are based on the National Electrical Code using copper connectors only. Field wiring must also comply with
local codes.
NOTE: Wye-Delta Compressor Start not available with this option.

NOTES:
1. Field wiring to be in accordance with the current
edition of the National Electrical Code as well as all
other applicable codes and specifications.
2. Numbers along the right side of a diagram are line
identification numbers. The numbers at each line
indicate the line number location of relay contacts.
An unlined contact location signifies a normally closed
contact. Numbers adjacent to circuit lines are the
circuit identification numbers.
3. Any customer supplied contacts must be suitable
for switching 24VDC. (Gold contacts recom-
mended.) Control Wiring must not be run in the same
conduit with any line voltage wiring.
4. To cycle unit on and off automatically with contact
shown, install a cycling device in series with the
flow switch (FSLW). See Note 3 for contact rating
and wiring specifications. Also refer to cautions on
the following page.
5. To stop unit (Emergency Stop) with contacts other
than those shown, install the stop contact between
5 and 1. If a stop device is not installed, a jumper
must be connected between terminals 5 and 1. De-
vice must have a minimum contact rating of 100VA
at 115 volts A.C.
6. Alarm contacts are for annunciating alarm/unit mal-
function. Contacts are rated at 115V, 100VA, resis-
tive load only, and must be suppressed at load by
user.
7. See Installation, Operation and Maintenance Manual
when optional equipment is used.
8. Control panel to be securely connected to earth
ground.
9. Us 2KVA transformer in optional transformer kit un-
less there are optional oil separator sump heaters
which necessitates using a 3KVA transformer.

CAUTION:
No Controls (relays, etc.) should
be mounted in the Smart Panel
enclosure or connected to power
supplies in the control panel.
Additionally, control wiring not
connected to the Smart Panel
should not be run through the
cabinet. This could result in nui-
sance faults.
CAUTION:
Any inductive devices (relays)
wired in series with the flow
switch for start/stop, into the
Alarm circuitry, or pilot relays
for pump starters wired through
motor contactor auxiliary con-
tacts must be suppressed with
YORK P/N 031-00808-000 sup-
pressor across the relay/
contactor coil.
Any contacts connected to flow
switch inputs or BAS inputs on
terminals 13 - 19 or TB3, or any
other terminals, must be sup-
pressed with a YORK P/N 031-
00808-000 suppressor across
the relay/contactor coil.
CAUTION:
Control wiring connected to the
control panel should never be
run in the same conduit with
power wiring.
