Use 3/8-16 Hardware’s for all slim line wall mount enclosures and 1/2-13 Hardware’s
for all Standard Wall mount and Floor mount enclosures mounting to fulfill Seismic
Requirements
For NEMA 12 enclosure types, liquid tight conduit and fittings shall be installed to
maintain the enclosure integrity.
GROUNDING
All field wiring shall be copper and have a minimum insulation rating of 75
C (167
F).
Size grounding conductors according to local and national codes.
Each panel contains a grounding bus with provisions for connecting a field-grounding
conductor.
All panels/enclosures must be grounded.
Grounding methods must comply to local and national codes.
POWER WIRE
(Greater than 120 VAC)
All field wiring shall be copper and have a minimum insulation rating of 75
C (167
F).
Size all wire based on panel nameplate current ratings in accordance with local and
national codes. Do not use the cable sizes listed in DET - 609 & DET - 610.
All power wiring must be routed away from other wiring. Avoid running power wiring
parallel to other wiring without a minimum separation distance of four (4) inches.
Power wiring should only cross perpendicular to other wiring.
Input and output power shall be connected as per the wiring diagram.
Incoming power cables should be terminated at line side of the lugs provided with the
Circuit breaker or Disconnect switch.
Locate terminals (T1, T2, and T3) in the panels and use these terminals to connect the
motor wires. Depending on actual drive panel configuration, motor cables should be
terminated on the load side lugs provided with the core drive (Disconnect drive or non-
bypass panel without load reactor), load reactor (Disconnect drive or non-bypass panel
with load reactor), contactor (non-bypass panel with load contactor) or overload relay
(all Bypass contactor configurations).
