Site Wiring
The cabinet’s AC power distribution boxes use common industrial wiring. Consider the following information when preparing the cabinet installation site:
•
•
•
AC power source – The AC power source must provide the correct voltage, current, and frequency specified on the manufacturer’s nameplate.
Earth ground – You must have an earth grounding conductor to the cabinet’s power receptacles.
Circuit overloading – Ensure the power circuits and associated circuit breakers provide sufficient power and overload protection. To prevent possible damage to the AC power distribution boxes and other components in the cabinet, use an external, independent power source which is isolated 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
•Power interruptions – The cabinet and its modules will withstand the following applied voltage interruptions (with or without an integrated UPS):
•
•
•
Input transient – 50% of nominal voltage
Duration – one half cycle
Maximum frequency – once every ten seconds
•Power failures – After a total power failure, the modules within the cabinet will automatically perform a
