Cable specifications for use in areas with severe electrical interference
The Promag 31 measuring equipment fulfils all general requirements for
electromagnetic compatibility (EMC) according to EN 50081 Part 1 and 2 /
EN 50082 Part 1 and 2 when installed in accordance with the NAMUR recommenda-
tions.
Note!
With the remote-mounted version (FS and FL) the signal and coil cables between
sensor and transmitter must always be screened and earthed at both ends.
This is done at the earth terminals inside the connection housing of sensor and
transmitter (see page 26).
