Planning for the Installation

Site Wiring and Power Requirements
The AC power distribution unit in the cabinet should use common industrial wiring.
Consider the following information when preparing the cabinet installation site.
O
AC power source
– The AC power source must provide the correct voltage,
current, and frequency specified on the equipment’s model and serial number
label.
O
Earth ground
– Site wiring must include an earth ground connection to the AC
power source.
O
Circuit overloading
– Power circuits and associated circuit breakers must 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 that is isolated from large switching loads (such as air
conditioning motors, elevator motors, and factory loads).
O
Power interruptions
– The cabinet and equipment will withstand the following
applied voltage interruptions (with or without an integrated uninterruptible
power supply [UPS]):
O
Input transient
– 50% of nominal voltage
O
Duration
– one-half cycle
O
Maximum frequency
–
once every ten seconds
O
Power failures
– If a total power failure occurs, when power is restored the
trays within the cabinet automatically perform a power-up recovery.
