Chapter 4. Equipment Installation
After completing the installation of the main bus splice bars,
the joint covers may be mounted and secured by a 3/8-16
nylon bolt and polyester flat washer if the bus insulation
option has been supplied with the equipment.
5. CONNECT THE TRANSFORMER SECONDARY - The
connection of the transformer secondary to the incoming
bus bars in the transition is made using the flexible
connection straps supplied with the transformer. These
connections are always bolted joints.
The recommended torque for tightening the ½-13 bolts
fastening the transformer connection straps to the incoming
bus bars is 35-40 ft-lbs.
6. INTERCONNECT ENTELLISYS CONTROL AND
COMMUNICATION WIRING - Interconnection of
control wiring across shipping splits is accomplished by
connecting to terminal blocks located in the cross-
section wiring trough on top of the equipment shown in
Fig. 4-14. Ethernet cables are connected by similarly
routing them across the top of the equipment and down
the gear, between the compartment side sheets.
If terminal blocks are provided, each wire must be attached
to the correct point on the terminal block, following the
circuit identification number attached to each wire.
