Site Wiring

The drive modules use wide-ranging, redundant power supplies that automatically accommodate voltages to the AC power source. The power supplies operate at a range between 90 VAC and 264 VAC, and at a minimum frequency of 50 Hz and a maximum frequency of 60 Hz. The power supplies meet standard voltage requirements for both domestic (inside USA) and international (outside USA) operation. They use standard industrial wiring with line-to-neutral or line-to-line power connections.

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 power-up recovery sequence without operator intervention after power is restored.
