Connection Diagram - WIKA A2G-20 Mode D'emploi

6. Commissioning, operation
Electrical connection
The instruments are designed to operate with safety extra-low voltage
(SELV). When wiring up the instruments, the technical specifications
for those instruments should be followed. In the case of a sensor with
GB
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
off must be prevented by the customer.
