In a redundant system one UPS may be isolated for service/maintenance without affecting other parallel UPS(s).

Action

1.Check that the remaining UPS(s) will be able to carry the load when one UPS is isolated.

2.Switch off the system to be isolated for maintenence by pushing the red OFF button.

3.Disconnect output and utility by setting output switches (Q002) to position 0 and input switch (Q001) to position 0. Disconnect battery by opening battery breaker.

2.7.2Switching Back the UPS to Normal Rarallel/Redundant Operation

Action

1.Set the input switch (Q001) and the output switch (Q002) to position 1.

2.Charge capacitors, connect battery, and start up the UPS as described in 2.4.1. Start UPS (from complete power down).

The UPS will automatically switch to normal operation and start load-sharing with the other parallelled UPS(s).
