AF-600 FP Design and Installation Guide
Description
•
Look for auxiliary equipment, switches, disconnects, or input fuses/circuit breakers that may
reside on the input power side of the adjustable frequency drive 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 adjustable frequency
drive.
•
Remove power factor correction caps on motor(s), if present.
•
Ensure that input power, motor wiring, and control wiring are separated or in three separate
metallic conduits for high frequency noise isolation.
•
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.
•
Measure to make sure that the top and bottom clearance is adequate to ensure proper airflow
for cooling.
•
Check for proper installation regarding electromagnetic compatibility.
•
See equipment label for the maximum ambient operating temperature limits.
•
Humidity levels must be 5%–95% non-condensing.
•
Check for proper fusing or circuit breakers.
•
Check that all fuses are inserted firmly and in operational condition and that all circuit breakers
are in the open position.
•
The unit requires a ground wire from its chassis to the building's ground.
•
Check for good ground connections that are tight and free of oxidation.
•
Grounding to conduit or mounting the back panel to a metal surface is not a suitable ground.
•
Check for loose connections.
•
Check that motor and line power are in separate conduits or separated shielded cables.
•
Inspect to ensure that the unit interior is free of dirt, metal chips, moisture, and corrosion.
•
Ensure that all switch and disconnect settings are in the proper positions.
•
Check that the unit is mounted solidly or that shock mounts are used, as necessary.
•
Check for an unusual amount of vibration.
