Start-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 input fuses rectifier F1, F2, F3 and battery fuses F9, F10, F11 are removed.
1. Insert the rectifier input fuses F1, F2, F3 and the battery fuses F9, F10, F11 (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
any one of the units
MENU/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 400 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
