Installation and Operation Unpacking
Unpack motor carefully and inspect for possible damage during
shipment. Check packing materials and save any instruction tags or
wiring diagrams found in the carton. Report any damages or
shortages immediately to the local transportation agent.
Before connecting motor to the electrical supply, inspect for any
damage resulting from shipment. Turn shaft by hand to assure free
rotation. If the motor has been in storage or subjected to adverse
moisture conditions, have it dried thoroughly before operating. After
drying, run motor (not connected to load) for a short time to assist
drying and as a bearing check.
Mounting
Mount the motor on a foundation sufficiently rigid to prevent
vibration. After careful alignment, bolt motor securely in place.
Mounting Instructions for 56C & 140TC Face Mounted Motors
Before mounting a “C” face motor to a mating flange, be sure both
surfaces and all mounting holes are smooth and free of debris.
When mounting into a quill type reducer, make sure the input and
output shafts are coated with an anti-seize compound suitable for the
application.
When mounting through a flexible coupling, verify that there is
adequate clearance between the driven equipment shaft, the coupling
interface and the motor shaft. Lack of clearance may result in binding
of the shafting and premature bearing failure.
Always slide the motor tenon into the mating flange to its full depth
before tightening the mounting bolts. Do not allow the motor to hang
by the shaft extension while assembling it to the driven equipment
(i.e. quill input gear case). This may bend or crease the shaft and
damage any seals that are present.
Only use the proper mounting bolts. These should be 3/8”-16 threads
per inch and sized for length such that engagement into the motor
flange does not exceed 9/16”. For example, a gear case with a 3/8”
flange thickness requires a bolt that is:
3/8” + 9/16” = 15/16” = Maximum Bolt Length.

ATTENTION: High voltage and rotating parts can cause
serious or fatal injury. The use of electric machinery, like
all other utilization of concentrated power and rotating
equipment, can be hazardous. Installation, operation, and
maintenance of electric machinery should be performed by
qualified personnel. Familiarization with NEMA safety
standards, national electrical code and sound local practices
is recommended.
