Against overvoltage
The battery back-up is equipped with anti-overvoltage safeguard at the input which
protects the circuits of receivers and the internal circuits of the UPS against
overvoltage caused by atmospheric phenomena and power grid disturbances.
Accumulator safeguards
Accumulators are protected by fuses. The terminal of the external battery module
and the internal accumulators are safeguarded separately. These safeguards also
function as disconnecting switches used e.g. during installation. Fuse type is
presented in the technical parameters table.
WARNING! Do not use fuses other than provided for in the device’s
specification!
Figure 6: Safeguards of internal accumulators
Users must follow the instruction written in the label below the fuses which mentions
the necessity of maintaining correct order of engaging the fuses. Connect F1 first,
wait 10 seconds and then connect F2. Failure to follow this instruction may damage
the battery back-up.
Terminal of the external battery module is safeguarded by the F5 fuse located to the
right of the clamps. With the holder open it disconnects the poles.
