PROTECTION
Overload protection
Overload (above 105%) is indicated by a continuous sound and a corresponding message on the
display.
If the overload is 105-120%, then the power supply unit will remain in the previous mode for one minute
before switching to BYPASS. If the overload exceeds 120% of the nominal power rating, the BYPASS mode
is switched on immediately. The unit remains in BYPASS as long as the overload continues above the
predefined limit. Once the overload discontinues, the unit attempts to restart five times. If they fail, the unit
switches to EMERGENCY mode. In BACKUP mode, an overload causes the unit to switch to EMERGENCY
mode without any additional attempts to restart.

Short circuit protection
A short circuit is indicated by
a corresponding message and a quick, intermittent beep If the short circuit lasts longer than a predefined limit
(hundreds of milliseconds), the unit switches to EMERGENCY mode.
(hundreds of milliseconds), the unit switches to EMERGENCY mode.
Surge protection
The unit features surge protection at the input, which protects the receiver circuits and internal circuitry
against high energy voltage surges caused by atmospheric phenomena and interference in the power
network.
against high energy voltage surges caused by atmospheric phenomena and interference in the power
network.
Battery protection
Batteries are protected with fusible links. The connection of the external battery pack (optional) features an
additional safeguard, as do the internal batteries. The safety device also serves as a disconnecting switch
that can be used during assembly.

Thermal protection
The unit is equipped with a thermal safeguard that protects it against overheating. There are two levels of
protection. If the internal temperature approximates a critical value, then a sound is emitted and a message is
displayed on the screen.
protection. If the internal temperature approximates a critical value, then a sound is emitted and a message is
displayed on the screen.
If the temperature keeps increasing, at the
critical value an alert message is displayed and the unit switches to EMERGENCY mode.
In the inverter-based modes, i.e. NORMAL, BACKUP, and HIBRID, there is an electronic short circuit protection
that in case of a short circuit limits, the short circuit current returns to its safe level.

The unit remains in the current mode.
NOTE! It is forbidden to use fuse links other than those listed in the device
