Procedure 4 -1 Procedure to Install Mounting Br ack et Assembly on a P ole
1
Slide non–buckle end of strap through openings in P ole Mounting Bracket
Assembly .
2
Set P ole Mounting Bracket Assembly with straps at the desired height.
Initial height is determined by customer . The bottom of the B CU
is a minimum of 1 meter from the ground. Adjust P ole/W all
Mounting Bracket Assembly to account for this minimum distance.
3
W rap strap around the pole, slide non–buckle end
through strap loop and around the pole again.
Slide end through strap loop and pull snug.
4
A ttach Bucklestrap Cutting T ool (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 T ool is a ratchet spindle and cutter
in one.
5
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.
6
Using the tool bend the strap over towards the buckle.
Remove tool and use a hammer to bend the strap more.
7
Use the hammer to bend buckle tabs over strap.
Use electrical tape to cover over the buckle and straps.
8
P erform step 3 through step 8 , for the remaining straps.
9
If not already attached to B CU , attach Mounting Bracket to B CU using nine
M6 bolts and washers (Refer to Figure 4-5 ). T orque bolts to 30 in–lbs (3.4

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 an y 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.
•S witching or disconnecting devices shall not be in the earthed circuit conductor
between the d.c. source and the point of connection of the earthing.
F or 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 P ower Cable
1
