Monitoring Relays
7/83
Siemens LV 1 T · 2006
3UG Monitoring Relays for Electrical and Additional Measurements
Level monitoring
■Technical specifications
1) Short-circuits without any contact welding acc. to
DIN VDE 0660 Part 200.
1) The sensor cable does not necessarily have to be shielded, but it is not
recommended to lay this cable parallel to the power supply lines. It is also
possible to use a shielded cable, whereby the shield has to be connected
to the M terminal.
