7.2.5 Reconnect a UPS unit to a Parallel System

NOTE:

The

Load

is still powered by the other units supplying the

Parallel Bus

This UPS unit will be powered on and connected to the

Parallel Bus

in order to share

the

Load

with each other's.

eBoost™

option is available, make sure that

eBoost™ Operation Mode

is disabled

before starting the shutdown procedure.

WARNING !

The

High Speed Bus Cable Connecting J52

(A) and

J62

(B) in any case cannot be

connected or disconnected after the system has been powered ON.
The

Bus Terminals

must be properly connected before powering the additional unit.

Open the front door, of the Unit to reconnect, and make sure that:

•

All the

connections

to the input/output bus bars of the UPS have been made correctly.

•

The

protection panels

are fastened in their correct position.

•

The

UPS Output Switch Q1

Manual Bypass Switch Q2

(option) and the

External

Battery Switch or

Fuses

must be open (Pos. O)

1. Switch-ON the Utility Voltage, on the Unit to reconnect, from the input distribution (both

Rectifier and bypass if separated).

At this stage the electronic power supply is switched ON.
