DE1600 Drive
Tray Site Wiring
and Power
The DE1600 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 preparing the installation site for the 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 drive
tray, isolate its power source from large switching loads, such as air-conditioning
motors, elevator motors, and factory loads.
 Power interruptions – The drive tray can withstand these applied voltage
interruptions:
— Input transient – 50 percent of the nominal voltage
— Duration – One-half cycle
— Maximum frequency – Once every 10 seconds
 Power failures – If a total power failure occurs, the drive tray automatically
performs a power-on recovery sequence without operator intervention after the
power is restored.
