Site Wiring and Power Considerations
The cabinet’s AC distribution boxes use common industrial wiring. Consider the following site wiring and power source requirements:
•
•
•
AC power source. The AC power source must provide the correct voltage, current, and frequency specified on the manufacturer’s name plate.
Earth ground. You must have an earth grounding conductor to the cabinet’s power receptacles.
Circuit overloading. Make sure the power circuits and associated circuit breakers provide sufficient power and overload protection. To prevent possible damage to the AC distribution boxes and other components in the cabinet, isolate its power source from large switching loads (such as air conditioning motors, elevator motors, and factory loads).
•Module power distribution. There are two accessory outlets inside the cabinet for module power distribution. All units attached to these outlets must be
