Rockwell Automation 1336T Master/Slave Parallel AC Drv - Manual (Page 20)

1336 FORCE-5.19 – August, 2000
3-2 Startup
Pre-Energization Checks Drive Inspection - Check the cabinets for any foreign objects such as
metal filings or metal foil, remove any debris.
Verify all connections are tight and connectors are properly seated.
Verify that TE and PE grounding is per supplied Allen-Bradley
drawings.
Motor Inspection - Check that the motor is bolted to the frame and
the frame is secured. Verify that the motor frame is grounded.
Check that the motor is uncoupled and coupling is secure and won’t
be damaged when rotating shaft. Turn the motor by hand to check for
binding.
Inspect motor junction box to verify it is clean and free of foreign
objects. Verify the connections are tight. Verify thermalguard wiring
if used.
Inspect encoder mechanical installation and verify encoder wiring.
Make sure the encoder alignment is correct. If a magnetic (e.g.
LakeShore) encoder is used, verify that the receiver heads are not
touching the encoder rotor.

ATTENTION: Working with energized industrial
control can be hazardous. Severe injury or death can
result from electrical shock, burn, or unintended
actuation of controlled equipment. Hazardous voltages
may exist in the cabinet even with the circuit breaker in
the off position. Multiple sources of power may be
connected to this drive. Recommended practice is to
disconnect and lock out control equipment from power
sources, and discharge stored energy in capacitors (if
present), before coming in contact with any equipment
in this cabinet. During startup it will be necessary to
work in the vicinity of energized equipment. The Safety
Related Practices of NFPA 70E, “Electrical Safety For
Employee Workplaces” must be followed at all times.
DO NOT work alone on energized equipment!

ATTENTION: This Drive contains ESD (Electro-
Static Discharge) sensitive devices. Static control
precautions are required when installing, testing,
servicing or repairing this assembly. If you are not
familar with static control procedures, before servicing,
reference Allen-Bradley Publication 8000-4.5.2
Guarding against Electrostatic Damage or any other
applicable ESD protection handbook.
