Auxiliary equipment Look for auxiliary equipment, switches, disconnects, or input fuses/circuit breakers that may reside
on the input power side of the frequency converter or output side to the motor. Ensure that they
are ready for full speed operation.
•
Check function and installation of any sensors used for feedback to the frequency converter
•
Remove power factor correction caps on motor(s), if present
•
Cable routing Ensure that input power, motor wiring and control wiring are separated or in three separate metallic
conduits for high frequency noise isolation
•
Control wiring Check for broken or damaged wires and loose connections
•
Check that control wiring is isolated from power and motor wiring for noise immunity
•
Check the voltage source of the signals, if necessary
•
The use of shielded cable or twisted pair is recommended. Ensure that the shield is terminated
correctly
•
Cooling clearance Measure that top and bottom clearance is adequate to ensure proper air flow for cooling
•
EMC considerations Check for proper installation regarding electromagnetic compatibility
•
Environmental consider- See equipment label for the maximum ambient operating temperature limits
ations
•
Humidity levels must be 5-95% non-condensing
•
Fusing and circuit Check for proper fusing or circuit breakers
breakers
•
Check that all fuses are inserted firmly and in operational condition and that all circuit breakers are
in the open position
•
Earthing (Grounding) The unit requires an earth wire (ground wire) from its chassis to the building earth (ground)
•
Check for good earth connections (ground connections) that are tight and free of oxidation
•
Earthing (grounding) to conduit or mounting the back panel to a metal surface is not a suitable
earth (ground)
•
Input and output power Check for loose connections
wiring
•
Check that motor and mains are in separate conduit or separated screened cables
•
Panel interior Inspect that the unit interior is free of dirt, metal chips, moisture, and corrosion
•
Switches Ensure that all switch and disconnect settings are in the proper positions
•
Vibration Check that the unit is mounted solidly or that shock mounts are used, as necessary
•
Check for an unusual amount of vibration
