EPO (Emergency Power Off)
An external Emergency switch (NC - Normally Closed voltage-free contact) can be connected on
terminals X2 / 1, 2 or connector J2 / 12, 25 of the Customer Interface (see Fig. 4.4.1-1 / X2 & J2).

NOTE !
To enable this function, remove jumper JP3 on the Customer Interface and the
cable on the terminal X2 / 1, 2 (see Fig. 4.4.1-2).
Verify if the cable on the terminal X7 / 1, 2 and jumper JP8 on the control board P2
– Mainboard are OFF (see Fig. 4.4.1-3).
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 follows:
•
Press the push-button EPO (contact on X7 / 1, 2 is closed again).
• Press the key “O” (Inverter OFF – see Section 6.2 of Operational Manual) on the control panel.
• Press the key “I” (Inverter ON – see Section 6.2 Operational Manual) 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.
