7.2.7 Restore to normal operation after “total off”

NOTE !

Make sure the all units of the parallel system to be status of the activation of “total off”, i. e. Q1 closed, Q2 open the battery fuses F5, F6, F7 (and eventual external fuses in case of external battery) connected.

1.Reset total offof the parallel system.

Restore the command “total off”, on any one of the units, by entering the screen: MENU/RESET TOTAL OFF

The load is supplied by the mains through the automatic bypass.

The booster starts automatically.

The LCD screen must display on all Units the status:

APPLICATION ON BYPASS

2.Switch ON the inverter on first unit by entering the screen:

MENU/COMMAND MENU/INVERTER ON

In case of sufficient output power, the output will transfer to Inverter.

3.Switch ON the inverter on the other units by entering the screen: MENU/COMMAND MENU/INVERTER ON

(Do not start the next inverter until the sequence of the previous one ends – about 10 seconds).

As soon as the output power of the inverters is sufficient to supply the load, the output of the units with running inverter will transfer to inverter.

The LCD screen must display on all Units the status:
