7.2.3Start-up following the operation on maintenance bypass (Q2)

This procedure presupposes that the load is powered by the manual bypass switch:

The inverter is switched OFF;

The manual bypass switch Q2 is switched ON (Pos. I);

The output switch Q1 is switched OFF (Pos. 0);

The battery fuses F5, F6, F7 (and eventual external fuses in case of external battery) are removed.

1.Insert the rectifier input fuses F1, F2, F3 and the battery fuses F9, F10, F11 / F13, F14, F15 (and eventual external battery fuses) on each unit.

2.Switch ON the output switch Q1 (Pos. I) on each unit.

3.Only in case it has been previously activated (* present beside the text RESET TOTAL OFF), restore the command total off on any one of the units by entering the screen:

MENU/RESET TOTAL OFF

LED TEST

 

RESET TOTAL OFF

*

4.Open the maintenance bypass switch Q2 (Pos. 0) on each unit.

Verify, selecting the screen METERING/Udcp and Udcn, that the booster voltage has reached about 215 VDC on each unit.

5.Switch ON the inverter on each unit 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).

The load will be automatically transferred from mains to the inverters as the needed power requested from the applied load is achieved on inverter side.

The main screen of each unit will display:
