of the cable is possible, using a single-lead cable 0,25...1,5 mm
Please take note that the use of a DC / DC-transducer calls briefly for a higher current
than the operating current when initially switching on the equipment. Therefore the power
supply must have enough low-impedance!

When making the connection, please make sure that the colour markings (white / black) are
correctly assigned!
The insulation of the coaxial cable should not be damaged and the shield should not come into
contact with the PE / protective conductor BE container potential. Shortening or lengthening the
probe cable is not recommended. Do not make any changes to the coax-cable or coax-connectors!
Pay attention to the correct allocation of the
