Complete UPS shut-down

Note!
Follow this procedure only in case the UPS system and the Load must be completely powered-

down.

If eBoost™ option is available, make sure that eBoost™ Operation Mode is disabled before starting
this procedure.

Initial status:

Load supplied by Inverter.

1. Perform the command

“

System shutdown”.

Perform the command “System shutdown” through

the screen:

Commands 1 / System shutdown /

SHUTDOWN

•

Load is disconnected from UPS.

•

Rectifier and Inverter are shut down and all contactors are
opened.

•

LED 1 (Rectifier) and LED 2 (Inverter) are OFF.

•

LED ALARM is lit.

2. Open the “Q1 – External UPS Output Circuit Breaker” (Pos. O).

3. Disconnect the Battery from the UPS by opening the “External Battery Breaker” (Pos. O).

Note!

Before performing the next procedure

(4) wait 5

minutes for DC-link Capacitors discharge.

Use the MEASURES/Rectifier screen to ensure that

the DC-link 1 and DC-link 2 voltage has reached
10Vdc.

Press “MUTE” key to reset Acoustical Alarm.
LED ALARM remains lit.

4. Disconnect the Utility from the input distribution.

End of Procedure

Danger!
It will take 5 minutes for the DC capacitors to discharge.
Open only the front door, do not open any other part of the UPS.
