Tray Site Wiring
and Power
The E5460 controller-drive tray uses wide-ranging, redundant power supplies that
automatically accommodate voltages to the AC 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 power connections or line-to-line
power connections.
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.
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 controller-drive tray can withstand these applied
voltage interruptions:
— Input transient – 50 percent of the nominal voltage
— Duration – One-half cycle
— 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.
