6.11.1

Replacement of UPS-Module in Single-Module systems

If your CONCEPTPOWER DPA 500 consists of only one single UPS-Module, the UPS needs to be
transferred to maintenance bypass. Follow the procedure of the
inverter operation to maintenance bypass first. Afterwards follow instructions in
here below
6.11.2

Replacement of UPS-Module in Redundant Multi-Module systems

THE OPERATIONS DESCRIBED IN THIS CHAPTER MUST BE PERFORMED
BY A SERVICE ENGINEER FROM THE MANUFACTURER OR FROM AN
AGENT CERTIFIED BY THE MANUFACTURER.
WARNING!
6.11.3

To extract a UPS module follow this procedure:

1. Reset the Alarm on faulty Module (if any). The chime sound will stop. If the Alarm condition
persists (the LED Indicator ALARM will remain red) it means that there is a fault in the UPS-
Module.
2. Make sure that the system is redundant.
3. Press both ON/OFF Buttons on the UPS-Module simultaneously. This will switch the module
off.
NOTE: The rest of the system remains on-line. THE LOAD IS STILL PROTECTED BY DPA 500
4. Open the Parallel Isolator Switch IA2 (switch to position "OFF") of the faulty module (if any). The
UPS-Module is now disconnected from output.
5. Open battery breakers F3- of the faulty module.
6. Unscrew the four screws on the front side of the module that are fixing it to the UPS-frame.
7. Pull Module only partially out, horizontally by means of the 2 black handles until the rear
connectors are disconnected.
THE WEIGHT OF A UPS MODULE CAN REACH 55KG, THEREFORE IT CAN
BE LIFTED ONLY BY 2 PERSONS. THE USE OF LIFTING TOOLS SUCH AS
TROLLEY WITH ADJUSTABLE HEIGHT OR SIMILAR DEVICES MAY BE
HELPFUL BY HANDLING MODULES.
NOTE
BEFORE DRAWING THE UPS MODULE COMPLETELY OUT, WAIT 5
MINUTES UNTIL THE INTERNAL DC-CAPACITORS ARE DISCHARGED.
WARNING!
8. To extract the module completely out, press down the two yellow tabs top-right and top-left of
the module (as shown in the figure here below) and then draw the UPS-module out by pulling
it out horizontally.
