1) If screened cable is used, the screen must be connected in the terminal box on one side to earth and the
earth terminal must be earthed outside on the housing according to the prescription. Both terminals are
connected in the housing.
3.2 Connection plan
Note:
A current meter for local control of the output current can be connected to terminals 1 and 3.
This measurement can be made during operation without interrupting the supply line.
Electrical connection
- If strong electromagnetic interferences
have to be expected, screened cable is
recommended. The screening should be
earthed at one side of the sensor.
- If overvoltages are expected, we recom-
mend the installation of VEGA-overvoltage
arresters.
- In the PG a seal must be used which fits to
the cable.
