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.
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.
