Basic Installation and Operation Guide
Incoming Line
On the standard JK, incoming power cable connections should
be made at the points shown on the wiring diagram furnished
with the equipment. These connections will normally be made in
a separate incoming compartment to bus lugs, an incoming load
interrupter switch, or a vacuum circuit breaker.
Load Connections
Outgoing load connections are made in the controller
compartment to the three copper pads located on the left hand
side wall.
Typical routing of load cables is depicted in Fig. 13 and Fig. 14
for top and bottom entry of cables, respectively.
Load cable termination arrangements for certain controllers,
such as reduced voltage autotransformer types, may differ from
those shown in this manual. In these cases, refer to the drawings
furnished with the equipment.
When routing and terminating load cables, observe the following:
-
Use listed compression connectors suitable for the cable
being used.
-
Use the 1/2" hardware provided with the controller to attach
cable connectors to bus pads. After installation, torque
hardware to 45 lb-ft.
-
After installation, check to see that at least three inches of
clearance is maintained between live parts of opposite
polarity and between live parts and ground.
