Site Wiring
The drive modules use
Consider the following information when preparing the drive module installation site:
•
•
Earth ground – The unit must be properly grounded, including an earth ground conductor on the AC power source.
Circuit overloading – Ensure the power circuits and associated circuit breakers in the cabinet and building provide sufficient power and overload protection. To prevent possible damage to the unit, isolate its power source from large switching loads (such as air conditioning motors, elevator motors, and factory loads).
•Power interruptions – The drive modules will withstand the following applied voltage interruptions (with or without an integrated UPS):
•
•
•
Input transient – 50% of nominal voltage
Duration – one half cycle
Frequency – once every 10 seconds
•Power failures – After a total power failure, the unit will automatically perform a
