Description
•
Check for loose connections
•
Check for proper fusing or circuit
breakers
Ensure that all switch and disconnect
settings are in the proper position.
The equipment requires a dedicated
ground wire from its chassis to the
plant ground. Check for good ground
connections that are tight and free of
oxidation.
Ensure the installation box and the
electronics part is properly closed.
Check that all four fastening screws are
tightened with the right torque.
Ensure the cable glands and blind
plugs are properly tightened, to
guarantee the right enclosure
protection degree is achieved. Liquids
and/or excessive dust ingress in the
drive can cause sub-optimal
performance or damage.
Ensure the equipment is not exposed
to a high level of vibration. Mount the
panel solidly or use shock mounts as
necessary.
