1) If screened cable is used, the screen must be connected to earth in the terminal box on one side and the
earth terminal must be earthed outside on the housing according to regulations. The terminals are connected
to each other 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 cable.
Electrical connection
- Screened cable is recommended if strong
electromagnetic interference is to be ex-
pected. The screening must be earthed at
the sensor end.
- If overvoltages are expected, we recom-
mend the installation of VEGA-overvoltage
arresters.
- In the PG, a seal must be used which fits
the cable.
