SOLUTION
It is advisable to replace the UPS batteries, as they are
no longer able to provide adequate backup power to the
load.
Warning: The batteries must be replaced by
qualified staff
Activate the maintenance bypass (SWMB) without
switching the UPS off, so that the fans will cool the heat
sink faster. Remove the cause of the overheating and
wait until the temperature of the heat sink lowers.
Exclude the maintenance bypass.
Insert the maintenance bypass (SWMB) without
switching off the UPS, so that the fans continue to
operate and cool the heat sink faster. Wait until the
temperature of the heat sink lowers. Switch off and
restart the UPS. Exclude the maintenance bypass. If
the problem persists, call the nearest service centre.
Remove the cause of the overheating.
Open the fuse holder switches (SWBATT) and wait until
the temperature of the battery charger heat sink lowers.
Close the battery fuse holders. If the problem persists,
contact the nearest service centre.
WARNING: never open the SWBATT fuse holders
when the batteries are operating.
Activate the maintenance bypass (SWMB) without
opening the INPUT/OUTPUT switches.
Turn off the 1/0 switch located behind the door, wait for
a few seconds and then turn it on again.
Restart the UPS. Exclude the maintenance bypass. If
the problem persists, contact the nearest service
centre.
Activate the maintenance bypass (SWMB). Set the 1/0
switch to "0". Wait for a few seconds. Return the 1/0
