7.2.6Complete shutdown of a parallel system

As a result of this procedure the parallel system is completely switched OFF and not powered.

NOTE !

This procedure involves all equipment powered by parallel system, to be shut down.

1.Perform the command total off on any one of the units.

2.Switch OFF the output switch Q1 (Pos. 0) on each unit.

3.Remove the battery fuses F5, F6, F7 (and eventual external fuses in case of external battery) on each unit.

4.In order to discharge the DC link capacitors, start once more the inverter on each unit through the screen:

MENU/COMMAND MENU/INVERTER ON

Remark: command INVERTER ON will be enabled only when the inverter voltage of each phase decreases below 7 VAC (about 30 seconds).

Before proceeding to step 5, check on the display panel that the DC link voltage (both polarities) Udcp and Udcn has reached the minimum voltage of 5 VDC (about 30 seconds).

5.Switch OFF the inverter on each unit entering the screen:

END OF PROCEDURE

CAUTION !

If the above procedure is not completely performed, it could cause serious damages to the UPS.

WARNING !

In case the procedure described on step “4 - discharge DC link capacitors” cannot be completely performed, the DC capacitors could be charged with dangerous voltage for about 15 minutes.

Wait until capacitors are completely discharged before starting the UPS again. Apart from the front door, do not open any other part of the UPS.
