Shutdown

Shutdown procedures in this section apply to the EPS 8000 UPS cabinet under normal, emergency, overload, and

maintenance conditions.

2.11.1 Emergency Shutdown Using EPO

CAUTION:

Pressing the EPO disconnects the attached load. The
emergency power off (EPO) is to be used during emergency
situations only, where a hazard to personnel or equipment
exists, such as during a fire. DO NOT USE THE EPO TO
TURN THE UPS OFF; follow the procedures listed in
this section for turning the inverter on and off.

During an emergency situation, such as a fire in the computer or electrical room, the UPS and all downstream

devices can be instantly shut down by pressing the “emergency power off” (EPO) pushbutton on the front panel of

the UPS cabinet, or by pressing the “remote emergency power off” (REPO) optional pushbutton located within the

room.

The EPO or REPO pushbuttons should not be used for normal shutdown of the equipment; when activated, ground

paths may be broken (depending on installation) and sensitive loads attached to the UPS may lose safety ground

connection.
