10.2.1 Remote EPO Input Port
The SmartOnline SV-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).

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.
