General; Maintenance Bypass - MGE UPS Systems Galaxy PW User Manual

Galaxy PW TM 100 to 225 kVA

general

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).

maintenance bypass

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".
