Procedure 4-1
Base Control Unit Installation
Procedure to Install Mounting Bracket Assembly on a Pole
Slide non–buckle end of strap through openings in Pole Mounting Bracket
Assembly.
Set Pole Mounting Bracket Assembly with straps at the desired height.
Initial height is determined by customer. The bottom of the BCU
is a minimum of 1 meter from the ground. Adjust Pole/Wall
Mounting Bracket Assembly to account for this minimum distance.
Wrap strap around the pole, slide non–buckle end
through strap loop and around the pole again.
Slide end through strap loop and pull snug.
Attach Bucklestrap Cutting Tool (slide strap through openings in tool,
pull gripper lever to slide strap into spindle head), slide tool towards
buckle. Place cutting tool end of tool as close to the buckle as possible.
The strap can be cut to a more manageable length prior to using
the tool. Bucklestrap Cutting Tool is a ratchet spindle and cutter
in one.
Turn spindle clockwise until strap is tight.
Bend the excess strap over tightened strap, cut strap, fold the cut tab into
the buckle, then close buckle.
Using the tool bend the strap over towards the buckle.
Remove tool and use a hammer to bend the strap more.
Use the hammer to bend buckle tabs over strap.
Use electrical tape to cover over the buckle and straps.
Perform step 3 through step 8, for the remaining straps.
If not already attached to BCU, attach Mounting Bracket to BCU using nine
M6 bolts and washers (Refer to Figure 4-5). Torque bolts to 30 in–lbs (3.4
N–m).

Objective
This section contains the procedure for installing the AC power cable.
This equipment uses dangerous voltages and is capable of causing death. Use extreme
caution when handling and testing this equipment. Earth connection is essential before
connecting the power due to the presence of high earth leakage current.
AC Cable Description
Cable E as listed inTable 3-1 is required for this installation.
The minimum bend radius for this cable is 90 mm.
Tools Required
The following tools are required to install the AC power cables.
•
No. 2 Blade screw driver
AC Power Connection Procedure
Follow the steps in Procedure 4-7 to connect a 100/240 VAC, Single Phase AC power cable to
the Base Control Unit (BCU). The AC power cable will be routed through one and one-half inch
conduit to the appropriate access hole on the underside of the BCU. The circuit breaker rating
ofr the AC Surge Protect is 25 A.
Branch Circuit protection to be provided during installation. A Single pole 25A rated circuit
breaker or adequately rated fuse shall be used for nominal 110/240 VAC installations." "For
supply connections, use wires suitable for at least 75°C" "Unit is intended for installation in
Restricted Access Locations"

AC or DC Power Cabling Installation
This equipment is designed to permit the connection of the earthed conductor of the
DC supply circuit to the earthing conductor at the equipment. If this connection is
made, all of the following conditions must be met:
•
This equipment shall be connected to directly to the DC supply system earthing
electrode conductor or to a bonding jumper from an earthing terminal bar or bus
to which the DC supply system earthing electrode conductor is connected.
•
This equipment shall be located in the same immediate area (such as, adjacent
cabinets) as any other equipment that has a connection between the earthed
conductor of the same d.c. supply circuit and the earthing conductor, and also
the point of earthing of the DC system. The DC system shall not be earthed
elsewhere.
•
The DC supply source is to be located within the same premises as the equipment.
•
Switching or disconnecting devices shall not be in the earthed circuit conductor
between the d.c. source and the point of connection of the earthing.
For supply connections, use wires suitable for at least 75°C.
Floating Supply voltage should not exceed 60 VDC for DC powered equipment.
Unit is intended for installation in Restricted Access Locations
Branch Circuit protection to be provided during installation. A single pole 50A rated circuit
breaker or adequately rated fuse shall be used for nominal -48 VDC installations. A Single
pole 80A rated circuit breaker or adequately rated fuse shall be used for nominal +27 VDC
installations.
Procedure 4-7
Procedure to Install AC Power Cable
Ensure that AC power at the source is disabled before handling cable.
AC power cables are supplied by the customer and should already
have been laid out at the site.
If not already done, route AC power cables through conduit to BCU Customer
Interface compartment.
In the BCU Customer Interface compartment, open the AC Surge Module
cover by loosening two captive screws. AC Surge Module cover is hinged.
Loosen screws on AC power terminal block. Insert AC power cables into
GROUND,LINE and NEUTRAL and tighten screws. See Figure 4-10
Ensure a good connection.
Close AC Surge Module cover and secure by tightening two captive screws.
If required, enable AC power at the source.
