3.15 Protective functions
Protective functions
Output overvoltage protection Typ. 58.5Vdc
Max. 60Vdc In the event of an internal power supply fault, a redundant circuit
limits the maximum output voltage. The output switches off and au-
tomatically tries to switch on again.
Protection class IP 20 EN/IEC 60529
Overtemperature protection Yes Output shutdown with automatic restart. The temperature sensor is
installed at critical components within the device and switches off
the device in safety-critical situations (e.g. load reduction require-
ments not met, excessive ambient temperature, ventilation blocked
or load reduction not observed if the mounting direction is different).
There is no correlation between the operating temperature and the
switch-off temperature, since the latter depends on the input volt-
age, the load and the installation type.
Protection against input transients MOV (metal oxide varis-
tor)
