Supply voltage

Electrical connection

The instruments are designed to operate with safety extra-low voltage

(SELV). When wiring up the instruments, the technical specications

for those instruments should be followed. In the case of a sensor with

transmitter, as a rule, the transmitter should be operated in the middle

of the measuring range, since deviations can occur at the range limits.

The ambient temperature of the transmitter electronics should be kept

constant.

The transmitters must be operated at a constant operating voltage

(±0.2 V). Current/voltage spikes from switching the power supply on or

o must be prevented by the customer.
