general maintenance bypass

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 recommend- ed to call the MGE UPS SYSTEMS after- sales support department.

■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 sys- tem is in on-line mode);

■if the load is no longer supplied with power, transfer it manually to the mainte- nance bypass (see section below).

This operation is possible only if the sys- tem 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. See section "maintenance configuration".
