Step #2:
Ensure that the equipment is allowed to stabilize at room temperature for at least
24 hours. The main intent is to ensure that any condensation that occurs as a
result of the ambient temperature changes is allowed to evaporate.
Qualified personnel must know how to quickly remove cabinet power before
continuing.
With cabinet doors closed, apply power to cabinet, closing main circuit breaker.
The main circuit breaker applies power to the input filter capacitors.
Qualified personnel should remain in visual contact of the equipment for at least
four (4) hours to aid the detection of the anomaly. The Variable Frequency Drive
(VFD) can remain in STANDBY, which occurs when main power is applied. It
does not have to be in RUN mode actually spinning a motor. Indications of the
anomaly include loud popping or hissing sounds, possibly followed by smoke; all
coming from the input filter capacitor bank.
If any anomaly is observed, immediately disconnect main power and replace the
input filter capacitor assembly. DO NOT continue with commissioning.
Continued degradation of the capacitors will occur.
If no anomaly is observed, follow the appropriate commissioning procedure that
was provided for this equipment.
