1.Stop the UPS with the OFF button 19 (press more than 3 seconds).

Check if UPS is on bypass AC source:

LED 17 is on (If LED 17 is not on, do not turn the manual bypass and call the after sales support department).

2.Turn the manual bypass switch 7 to the BYPASS position.

3.Switch the battery circuit breaker(s) 14 to the OFF position.

CAUTION: Do not switch the Normal AC source circuit-breaker 8 to the OFF position. Doing so will disconnect power to the load.

4.Loosen three screws to remove the Input/Output box.

5.Disconnect the battery cables 40 and 42 from the power module.

The power module can be replaced.

The connected equipment is powered by the Bypass AC source.
