5. Commissioning, operation
5.2 Electrical mounting
The instrument is designed to operate with safety extra-low voltage
(SELV). As a rule, operate the dierential pressure transmitter in the
middle of the measuring range, since deviations can occur at the range
limits.
Operate the A2G-50 with a constant operating voltage (±0.2 V) and
ambient temperature. Prevent current/voltage spikes from switching the
power supply on or o.
For CE conformity, a properly grounded protective cable is required.
1. Unscrew the strain relief and feed the cable(s) through.
2. Connect the wires (see “Connection diagram”).
3. Tighten down the strain relief.
