panel enclosure. See the mechanical layout
drawing located on the inside cover of the unit
for locations to connect power and motor wiring.
•
Removable access covers are provided for cable
connections (see figure Conduit Entry Diagrams).
Remove access covers before drilling holes to
prevent metal shavings from damaging internal
electronic components.

For some units, access holes are provided for
input power, motor leads, and control wiring.
•
Run input power, motor wiring, and control
wiring in three separate conduits for isolation.
