To enable this function, remove jumper JP3 on the Customer Interface and
the cable on the terminal X2 / 1, 2 (see Fig. 10.2.1-2).
Verify if the cable on the terminal X7 / 1, 2 and jumper JP8 on the control
board P2 – Mainboard are OFF (see Fig. 10.2.1-3).
In a parallel system a separate NC (Normally Closed) contact must be connected
individually to each unit.
When activated, this switch causes the immediate shutdown of booster, battery-charger, inverter;
and the contactors K4, K6 and K7.
NOTE !
This procedure could imply a load shutdown.
When the EPO has been activated, the system must be restored as following:
• Press the push-button EPO (contact on X2/1, 2 is closed again).
