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
