5.2 REPLACEMENT OF UPS-MODULE
5.2.1 Replacement of UPS-Module in Single-Module Systems
THE OPERATIONS DESCRIBED IN THIS CHAPTER MUST BE
PERFORMED BY A SERVICE ENGINEER FROM THE MANUFACTURER OR
FROM A AGENT CERTIFIED BY THE MANUFACTURER.
5.2.1.1 How to Extract a UPS-Module in SINGLE MODULE Systems
The weight of a UPS module can reach 22kg, therefore it can be lifted by 1
person. We recommend two persons for carrying the module .
Potential dangers:
the ups module due to its weight, if removed inappropriately, can cause
serious injury or damage should the module fall down.
note:
we recommend that the modules are handled by two persons.
SUITABLE LIFTING TOOLS RESPECTIVELY SAFEGUARD PLATFORMS
AGAINST EVT. FALL DOWN ARE TO BE PLANNED.
If your DPA UPScale
TM
consists of only one single UPS-Module then perform following steps to extract the module:
1. Reset the Alarm on faulty Module. The audible noise 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. If the load is supplied by the mains in Bypass-Mode (Eco-Mode) the Maintenance Bypass (IA1) may
be closed by turning it to position “ON”.
NOTE: If the load is on inverter, then before closing the Maintenance Bypass IA1, transfer load to
bypass by means of the command “LOAD TO BYPASS” in submenu COMMANDS. On LCD: “LOAD
NOT PROTECTED” will appear.
3. Close Maintenance Bypass Switch IA1 (position ON)
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
