if it is necessary to replace any connection cables, original materials have
to be purchased through our KESS Service or authorised distributors. Using
inappropriate cables can lead to overheating and fire hazards. Inside the
device there are permanent dangerous voltages even without mains supply
through its connection with the batteries and especially in UPS devices where
the electronics and batteries share the same housing.
Therefore it is irrelevant if the input circuit breaker of the fuse box and/or input of
the device for the models > 3 kVA is in posititon ‘off’.
Mind that the battery circuit is not isolated from the input voltage, so there is a
risk of discharge with dangerous voltages between the battery terminals and
the earth terminal, which is in turn connected to the earth (any metal part of the
device).
Repair and/or maintenance must be carried out by our KESS Service. The
replacement of batteries may only be performed by qualified personnel.
Depending on the configuration of the UPS, certain actions have to be carried
out before handling batteries:
1) UPS with batteries and electronic in the same housing:
