7.2.5Start-up an additional unit in a parallel system

Before connecting hazardous voltages, make sure that:

The connection to the electrical system has been performed by qualified personnel;

The equipment frame has been correctly grounded to the main earth;

Make sure that mains input protection is removed;

All the panels removed to allow the UPS connection have been correctly reinstalled;

The UPS switches Q1 and Q2 are OFF (Pos. 0);

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

This procedure must be performed when the load is supplied by the other units of the UPS system and an additional unit must be switched ON and connected to the parallel bus in order to share the load with each other.

This unit must be completely switched OFF and not powered.

1. Switch ON the mains power at the input distribution pane on

EXECUTING MAINBOARD

this unit.

SELF TEST

As a result the UPS performs a self-test and the LCD will show

00000000000

the following screen:

SELF TEST OK!

 

 

NOTE !

In case the alarm “4410 - Mains bypass out of tolerance” persists, please contact your Service Center.

2.Insert the battery fuses F5, F6, F7 (and eventual external fuses in case of external battery) on this unit.

3.Switch ON the output switch Q1 (Pos. I) on this unit.

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

4.Switch ON the inverter of this unit entering the screen:

MENU/COMMAND MENU/INVERTER ON

When the inverter will be synchronized, the unit will be automatically connected with the parallel bus-bar and the load will be shared with the other units.

The main screen of each unit will display: APPLICATION ON UPS
