, with open front door: Switches

and

must be open

(Pos. O).

1. Connect the Utility power on all UPS’s.

(In case of separate inputs for

Rectifier

and

Bypass

, connect both).

•

Power supply starts up. Indicated with flashing

alarm

and

buzzer sounds

•

LED’s as indicated will be lit.

•

Press

mute

, to reset

alarm and buzzer

First operated unit

All other units of the system

2. Close Q1 (Pos. I) on all Units

•

When closing

on the last unit of the parallel system, the

Bypass

Units

connects to the

Load

•

Rectifiers

start automatically, blinking

LED

indicates Soft-start.

•

At the end of

Rectifier

Soft-start, the

LED

remains lit.

•
