mode) only when the overload falls below the set level (CONFIGURATION
3/4;ProgKas.Prz.).
If in NORMAL operation mode the overload rises to 105%, the unit will start signalling
this development by a continuous sound and the appropriate message on the
display. As in the case of BACKUP mode, this state will last until the overload falls
below the set level (CONFIGURATION 3/4;ProgKas.Prz.). In NORMAL mode there is
no time limit (as opposed to the BACKUP mode). In NORMAL mode, the parameters
of power line fusible cut-out F4 function as the upper overload limit.
Short circuit protection
In BACKUP mode there is an electronic short-circuit protection which, when a short-
circuit occurs, limits the short-circuit current to a safe level. The occurrence of
a short-circuit is indicated by the corresponding message and a rapid, intermittent
sound signal. If the short-circuit lasts in excess of 100 ms, the power supply unit
switches to EMERGENCY mode.
The input power lines (primary line and service bypass line) are protected by
automatic fuses (fuses with designations F3 and F4).

Surge protection
The power supply unit is fitted with surge protection at the input, which protects the
circuits of receivers and the internal circuitry of the unit against overvoltage caused
by atmospheric phenomena and interference in the power grid.
Battery protection
Batteries are protected with fusible cut-outs. The terminal of the external battery
module and the internal batteries are protected separately. This safeguards also
function as disconnectors, which are used - for example - during installation,
transport or storage. The fuse type is specified in the technical parameters table.
NOTE! It is prohibited to use fuses other than set forward in the
device specification.
