1 - Press a button to exit sleep mode.

2 - Shut down the UPS by pressing the OFF button (38) for 3 seconds. 3 - Set bypass switch Q3BP (10) to ON.

4 - Set output switch Q5N (11) to OFF.

5 - Set the battery circuit-breaker QF1 (13) (or set the battery circuit- breakers of the auxiliary cabinets if any) to OFF.

6 - Set the input circuit-breaker Q1 (8) to OFF.

7 - Set the input circuit-breaker Q4S (9) to OFF.

8 - Wait until the display and LEDs go off.

The load is no longer protected by the UPS, but continues to be supplied with AC power.

UPS maintenance or servicing can now be carried out.
