Function
4.1 Operating principle
The PE CON+ ® determines the availability of the protective earth of single and 3-phase networks by
measurement.
If the protective earth is available, an internal release relay (potential-free contacts) is actuated. A
separate line contactor can now be switched via the signal contact in order to supply the
consumer(s) with voltage.
4.2 Normal state
When the PE CON+ ® is ready for operation, the green LED "OK" on the front cover is illuminated and
the "Betrieb" (“Operation”) signal contact is activated.
For the PE CON+ ® NVT and PE CON+ ® NVF models, two internal release relays are activated
(signal contacts “Freigabe-Relais 1” ("Release relay 1") and “Freigabe-Relais 2” ("Release
relay 2").
