If the overload exceeds 120% of the rated power and the function "switch to BYPASS
if overloaded" is enabled, the UPS unit will promptly switch to the BYPASS mode
(message A64). When the overload condition ceases, the unit remains in the
BYPASS mode. If the function "switch to BYPASS if overloaded" is disabled, output
sockets are promptly disconnected. The LCD displays message E14 and a
continuous sound signal is generated.
Short-circuit protection
In the mains mode, the fuse located in the UPS unit's rear section acts as a short-

limits the short-circuit current to a safe level. The UPS switches to the EMERGENCY

Against overvoltage (Anti-surge)
The UPS unit is equipped with anti-surge protection on input to protect circuits of the
connected load(s) against potential voltage surges resulting from weather conditions
and interference in the power network.
Thermal protection

overheating. This thermal protection operates in two stages. If the temperature
approaches a critical level, the message E19 appears on the display and a sound
signal is generated every second. The UPS unit continues to operate in the selected
mode. If the temperature continues to increase and reaches a critical value, the
message A68 is displayed and the UPS unit switches to the EMERGENCY mode.
