CONNECTING EQUIPMENT TO OUTLETS
Critical equipment is connected to the uncontrolled outlets so they remain on until the UPS battery is depleted. Noncritical equipment is connected
to controlled outlets so they can be set to turn off once the battery is depleted to a set level. Controlled outlets can also be set to remain on for
additional critical loads. Use the remote management connection or the front panel LCD to configure the controlled outlets.

EPO
Circuit
EMERGENCY POWER OFF (EPO)
The EPO feature uses a simple open/closed circuit that, when opened, causes the UPS to immediately shut off power to all outlets. By default, a
metal jumper is placed between the contacts of the EPO connector. Remove the jumper and wire a normally closed switch to the connector to use an
installed EPO switch.
EPO Reset
To restore normal operation after engaging EPO, the UPS must be turned off and then back on using the front panel LCD buttons.
USB/RS-232 PC CONNECTION
For easy monitoring and configuration of the UPS, plus the ability to shut down the connected computer before the battery depletes.
20A, 120Vac
Connect to computer USB
or serial port. Only one
port may be connected.
