1 - On each UPS unit, press a button to exit sleep mode.

2 - Shut down each UPS unit by pressing their OFF buttons (38) for 3 seconds.

3 - Set switch Q3BP (65) in the external bypass cabinet to ON.

4 - Set switch Q5N (66) in the external bypass cabinet to OFF.

5 - Set switch Q4S (64) in the external bypass cabinet to OFF.

6 - Set output switch Q5N (11) of each UPS unit to OFF.

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

8 - Set the input circuit-breaker Q1 (8) of each UPS unit to OFF.

9 - Set switch Q4S (9) of each UPS unit to OFF.

10 - Wait until the control electronics of all UPS units have fully shut down.

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

Maintenance or servicing can now be carried out.
