Enable input X1
This function is not available with P30 e-series.
The enable input X1 is equipped for use with a potential-free contact. Using
the enable input, it is possible to control the charging station using external
components (e.g. external key switches, house control, photovoltaic system,
ripple control receivers, ...). The terminal is designed as a spring-type termi-
nal.

The use of the enable input must be activated with a DIP switch setting
(DSW1.1 to ON), see

In addition to the DIP switch setting, starting a charging process using an en-
able input is dependent on the RFID authorization. The table shows under
which conditions charging is enabled.
