4.10 Alarms
The auto diagnostic system considers any system status other than normal as a problem.
Before taking any action , note down the messages displayed on the control panel.
Certain problems may prevent the control panel from functioning.
In this case, it is strongly recommended to call the MGE UPS SYSTEMS Customer Support Service at:
1-800-438-7373.
A) If the load is still correctly supplied with power, it has probably been transferred to the bypass AC source (static
bypass) and is therefore no longer protected (if the system is in on-line mode).
B) If the load is no longer supplied with power, transfer it manually to the maintenance bypass.

4.11 Maintenance Bypass Option
The Maintenance bypass option provides a direct bypass AC input source (mains 2) that can be used to supply the
critical load while the UPS is being serviced.
This operation is possible only if the system includes a bypass AC source. It results in the load being directly
supplied by the Bypass AC source via Maintenance Bypass switch Q3BP, thus ensuring a higher level of security in
the event of a malfunction.
Switching procedures are explained on drawings next to each switch in the UPS cabinet and the External Bypass unit.
