9.4 Voltage pre-charging
NOTICE
In order to avoid the formation of sparks as well as damage to the device during activation, the
connected consumer loads must always be pre-charged via a pre-charging resistor.
When using a PTC as pre-charging resistor, it is heated by means of multiple subsequent pre-
charging processes. If the PTC overheats, another pre-charging process is temporarily
impossible. In this case, the pre-charging resistor has to be cooled down for a certain period of
time.
If the system is only connected to one power source at the highside, the pre-charging unit on the highside is
sufficient.
