NOTE !
To enable this function, remove jumper JP3 on the Customer Interface and the
cable on the terminal X2 / 1, 2 (see Fig. 4.4-2).
Verify if the cable on the terminal X7 / 1, 2 and jumper JP5 on the P1 – Control
board are OFF (see Fig. 4.4-3).
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.
