Input Power Wire Installation
Note: The L1, L2, and L3 input power leads for this unit
will be connected to a factory installed input
disconnect circuit breaker inside of the drive
cabinet.
1. D-Frame Only: Remove the conduit shroud from the
cabinet to fully expose the two-piece incoming wire
access door on the top of the cabinet.
2. Remove the access door pieces and take them to
another location for marking and drilling the required
wire routing holes for the input wire leads.
Note: These
wire routing holes are the only entry
points that should be used for bringing input
power wiring into the drive cabinet.
Note: In some cases, the top plate with conduit hubs
from the original starter may be reused and
installed over the incoming wire access cut-out
on the top of the cabinet, in place of the two-
piece access covers.
a. Install the appropriate conduit hubs before
reinstalling the access door pieces on top of the
cabinet.
3. Route the input wire leads into the cabinet and connect
them
to circuit breaker terminals L1, L2, and L3.
a. The torque specification for these terminal
connections is 31 ft·lb.
