Site Wiring Requirements

Review the following information when preparing the drive module or E2400 command module installation site.

•

•

Earth ground – The unit must be properly grounded, including an earth ground conductor on the AC power source.

Circuit overloading – Make sure 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).

•Power interruptions – The drive module or E2400 command module will withstand the following applied voltage interruptions:

•Input transient: 50% of nominal voltage

•Duration: one half cycle

•Minimum frequency: once every 10 seconds

•Power failures – Once power is restored after a complete power failure, the unit automatically performs a power-up recovery sequence without operator intervention.

Site Wiring and Voltages

The drive modules and E2400 command module use wide-ranging, redundant power supplies that automatically match voltages to the AC power source. They are a 120/220 VAC, 50/60 Hz units that meet standard voltage requirements for both domestic (USA) and international (outside USA) operation. They use standard industrial wiring with a line-to-neutral or line-to-line power connections (Table 10).
