10.2.1 Remote EPO Input Port

The SmartOnline SVX-Series UPS includes an Emergency Power Off (EPO) function for site safety. This may be operated via a user-provided
remote contact. User may define the logic (NC – Normal Close, or NO – Normal Open) for the EPO function via the LCD panel (see Section
9.3.6.1: General).
Logic

NO
For normal UPS operation, keep pins 1 and 2 open. To enable EPO operation, close contact between pins 1 and 2. The default EPO setting is NO,
for normal UPS operation.
Note: Activating EPO shuts down the UPS system rectifiers, inverters and STS. The input power supply is not internally disconnected.
