Pressing the "Emergency Power Off" (EPO) pushbutton disconnects
the attached load. The 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 ON OR OFF. Follow
the procedures listed in this section for turning the Inverter on and off.
Using the forced transfer functions will cause the load to experience a
power interruption for a minimum of 500 milliseconds. Be certain that
the load can tolerate this interruption.
