extract the module:
1. Reset the alarm on the 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.

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
