• EPS in bypass mode
• EPS in operating mode
The contacts of the relay interface are programmed in default mode as normally open (NO) and with specific signalling
functions. These settings can be changed by means of the control panel (see section 6.4.2 - path UPS Setup 

5.3 Emergency Power Off (EPO)
The EPS has an external normally closed contact (NC) that can be opened to activate the immediate stop of the equip-
ment.
The EPO terminal is at the back of the EPS on pins 3 and 4 of the 6-pole connector of the relay interface.
For the correct connection of the EPO, the following requirements must be adhered to:
- use a double-insulation cable of up to 10 meters in length;
- check that the switch used is galvanically isolated.
