Voltage pre-charging
INSTRUCTION
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, the latter is heated by means of multiple subsequent
pre-charging processes. If the PTC overheats, another pre-charging process is temporarily
impossible. The pre-charging resistor must be cooled down for a certain period of time in such
case.
