Tray Site Wiring
and Power
The E5500 controller-drive tray uses wide-ranging, redundant power supplies that
automatically accommodate voltages to the AC power source or the optional
–48-VDC power source. The power supplies meet standard voltage requirements for
both North American (USA and Canada) operation and worldwide (except USA and
Canada) operation. The power supplies use standard industrial wiring with
line-to-neutral or line-to-line power connections.
NOTE Power for the optional –48-VDC power configuration is supplied by a
centralized DC power plant instead of the AC power source in the cabinet. Refer to the
associated manufacturer’s documentation for specific DC power source requirements.
Keep this information in mind when you prepare the installation site for the
controller-drive tray:
 Protective ground – Site wiring must include a protective ground connection to
the AC power source or the optional –48-VDC power source.
NOTE Protective ground is also known as safety ground or chassis ground.
 Circuit overloading – Power circuits and associated circuit breakers must
provide enough power and overload protection. To prevent damage to the
controller-drive tray, isolate its power source from large switching loads, such as
air-conditioning motors, elevator motors, and factory loads.
