EMERGENCY POWER OFF/ WITHOUT VOLTAGE
This is small Phoenix Green connector that is inserted in the receiver receptacle located on the front of the UPS,
just below the USB port. This small Green 2 pole connector is inserted into the UPS.
The EPO only requires dry contact closure N/C. The UPS will shut down, including the ability to supply output
power to any type of load. (THE SHUT DOWN HAS A DELAY OF ONLY 1 SECOND)
The UPS will not restart unless the applied signal is changed to N/O. In other words the EPO must be reset or
removed.
NOTE: ALARM CODE ER-000 will be present when the EPO is used or latched.!!
When the applied signal has been removed, the UPS must be reset because this is a latched alarm.
Meaning that you must disconnect the AC and DC, then reconnect and restart the UPS normally..
