EPO and Remote Shutdown

EPO (Emergency Power Off): TB1-14, -15
The EPO is a NO (Normally Open) dry contact switch. When the EPO is closed, the Input circuit breaker to the UPS
opens and all power to the unit is removed, including backup power from the batteries.
Remote Shutdown: TB1-16, -17
The Remote Shutdown is a NO (Normally Open) dry contact switch. When the Remote Shutdown switch is closed, the
UPS transfers from Normal/Backup to Bypass after a 1 – 2 sec. detection delay. (See the diagram below)
When the closed Remote Shutdown switch is opened, the UPS transfers from Bypass back to it's initial state (Normal/
Backup) after a 1 – 2 sec. detection delay.
If the UPS is in bypass when the Remote Shutdown is closed, no action is taken.

Battery Cabinet Connections

Optional external battery cabinets can be used to extend the backup time of the UPS beyond that available with the internal
batteries. The external battery cabinets connect to the UPS via Anderson-style connectors. See Section 20.
