SAFEGUARDS
Against overloads
Overload is signalled by constant shining of the last LED (red) in the load indication
column and a continuous sound signal. If the UPS is operating in battery module
mode then after a short time the overload causes the UPS to switch to emergency
operation mode.
In addition, the UPS is equipped with internal safeguards against overloads and
shorting of the battery circuit.
Against shorting
In the mains operation mode the safeguard against shorting is provided by the circuit
breaker located in the rear section of the UPS.
If the shorting occurs in the battery operation mode, the output current is limited to a
safe level. This is signalled by a quick blinking of the last LED (red) in the load
indication column and a quick, intermittent sound signal. If the shorting lasts longer
than 0.5 second, the UPS switches to the emergency operation mode.
Against overvoltage
Devices connected to the UPS are protected against mains overvoltage. This solution
protects the receivers against impulse current rushes caused by atmospheric
phenomena or power grid disruptions.
Against incorrect connection
Incorrect connection of the UPS causes it to switch to emergency operation mode the
moment it is switched on. Such an event is signalled by slow blinking of the last LED
(red) in the load indication column and an intermittent sound signal mirroring the rate
of blinking. In addition, the layout of lit LEDs in the battery charge level column
indicates the type of error. (see the Error Table below)
