Electrical contact rating for optional thermo-switch: 12 / 24 V DC, 3.0 A
CAUTION
The fittings and flanges must be conductively connected with the tank and integrated in the
potential equalization system.
CAUTION
If various electrical components (e. g. reed switch and temperature switch) are used in a level
switch, the electrical values of the weakest component must be observed.
No different potentials must be used.
