EPO (Emergency Power Off)
An external Emergency switch (NC - Normally Closed voltage-free contact) can be connected on

Fig. 10.2.1-2 PCB Customer Interface
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.
