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

NOTE !
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 JP5 on the P1 – Control board
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.
When the EPO has been activated, the system must be restored as follows:
•
Press the push-button EPO (contact on X7 / 1, 2 is closed again).
•
Press the key "O" (Inverter OFF – see Section 6.2) on the control panel.
•
Press the key "I" (Inverter ON – see Section 6.2) on the control panel.
In case of a Parallel System press the key "O" (Inverter OFF) on the control panel of
each unit connected on the parallel bus and having its output switch Q1 closed.
