Auxiliary power connection

According to EN 60204, Section 8, the
addition to the supply voltage connections X1/1,2.
With respect to the wall-mounted transmitter, the potential equalization connection on the
attachment flange can also be used to connect the protective conductor.
7.2.2

Connection of current outputs for conductivity and temperature

In order to avoid current signal interference, a screened line (eg. LiYCY) is recommended. The
shielding wire should be connected at the programmable controller to the PE connection. In the

To ensure compliance with protective enclosure IP 67 specifications, the scope of
delivery includes various sealing inserts for the PG 13.5 mm threaded unions for cables
from 4 to 10 mm diameter. Unused PG unions must be sealed.
