AN 12-1007, Rev.03, 04/04/2012
GROUNDING
All panels/enclosures must be grounded.
All exposed metal parts are
connected to ground to prevent contact with a dangerous voltage if
electrical insulations fail.
Each panel contains a grounding bus with provisions for connecting a
field-grounding conductor.
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
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 manuals.
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 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 of the Power
Distribution Blocks.
Refer to Appendix B for Tightening torque details for motor connections.
CAUTION:
Failure to cover components from metal shavings may
result in damage to equipment.
