we remind you that all isolation transformers, installed or delivered ex
factory, have the output neutral grounded through a bridge between the
neutral terminal and ground. if the isolated output neutral is required, this
bridge must be removed considering the respective local and/or national low
voltage regulations.
•
This device is suitable for installation in networks with TT, TN-S, TN-C or iT
power distribution systems. Please consider the specific features of your used
device and national electrical regulations at any times.

The KESSUPS models contain batteries in its UPS housing.
The battery protection of the device and of any accumulator module has to be
carried out by internal fuses, so that it is not accessible to the user.
important for your safety: if you install the batteries by yourself, the
accumulator group must be fitted with a bipolar circuit breaker or disconnection
fuse as described in Tab. 2. inside the battery module, there are hazardous vol-
tages with the risk of electric shocks. Thus it is classified as a area with restricted
access.
Under no circumstances handle the fuse holder or battery circuit breaker if the
device is in operation.
if the power supply of the device or the parallel systems is cut for longer than a
simple intervention and it is expected that it will be out of service for a prolonged
period, the system must be shut down completely.
The battery circuit is not isolated from the input voltage. dangerous voltages can
occur between the terminals of the battery group and the earthing. Check that
there is no input voltage before intervening on the terminal.
