5.2.3 Replacement of a Module in Capacity Multi-Module System
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
5.2.3.1 How to Extract a Module in a Capacity Multi-Module System
If in capacity parallel system a UPS-Module experiences a fault and there is not enough capacity left to protect
the load by the remaining operating UPS-Modules, the load will automatically be transferred to bypass
(Bypass-Mode or Eco-Mode) and will continue to be supplied by the mains power supply.
To extract the faulty module from the UPS-Frame in a Capacity Multi-Module System 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 the load is on Bypass and is supplied by the mains power (Bypass-Mode or Eco-Mode) on
all UPS-Modules; in the majority of the events the LED-indicators on Control Panel of the Faulty
Module will show:
3. Whereas the LED-indicators on the Control Panels of the other Operating Modules will show
4. Close Maintenance Bypass Switch IA1 (position ON)
5. On LCD: “MANUAL BYP IS CLOSED” will appear and the LED-indicator will indicate as shown
below:
The load is now directly supplied by mains and is not protected
6. Press both ON/OFF Buttons on UPS-Module to be replaced simultaneously;
7. Open corresponding battery fuses
8. 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.
