5.2.2 Replacement of UPS-Module in Redundant Multi-Module System
WARNING!
THE WEIGHT OF A UPS MODULE CAN REACH 22KG, THEREFORE IT IS
RECOMMENDED TO BE LIFTED BY 2 PERSONS. THE MODULE SHALL
NEVER BE CARRIED BY ONE PERSON ONLY.
WARNING!
MAKE SURE THE INTERNAL DC-CAPACITORS (ELCO) HAVE BEEN
DISCHARGED WAITING AT LEAST 5 MINUTES. HOW TO EXTRACT A
MODULE IN REDUNDANT MULTI-MODULE SYSTEM
5.2.2.1 How to Extract a Module in Redundant Multi-Module System
If in a redundant parallel system a UPS-module is faulty, the load will continue to be protected by the operating
modules On-Line-Mode (Inverter-Mode) and the faulty Module may be replaced without having to transfer the
load to bypass!
To extract the faulty module from the UPS-Frame in a Redundant Multi- Module Configuration proceed as
follows:
1. Identify the faulty Module with the Alarm condition and RESET the Alarm. The audible noise will stop.
If the Alarm conditions persists (the LED-Indicator ALARM is red) there is a fault in the UPS-Module.
2. Verify that load is supplied by inverter of the other modules running by checking the LCD indication
LOAD PROTECTED. Verify load measures on the operating modules.
3. Turn the faulty module OFF by pressing simultaneously both “ON/OFF” buttons.
On the LCD: “LOAD OFF, SUPPLY FAILURE” should appear and the LED-indicator will indicate as
shown below:

4. Remove the two fixation screws and slide out the UPS-Module (10cm)
This operation will disconnect module by the power connection located on the back of the cabin.
5. Pull the module out.
ATTENTION: BEFORE DRAWING THE UPS-MODULE COMPLETELY OUT, WAIT 5 MINUTES UNTIL
THE INTERNAL DC-CAPACITORS ARE DISCHARGED.
NOTE: We recommend 2 persons for pulling out the module from the UPS-Frame. The weight of a
of UPScale M10 is 18.5 kg, M20 module is 21.5kg)
6. Screw the protection cover on the empty area left empty by the module with the two fixation screws.
