Wiring
Type 8025 / 8035
8.4.5. Wiring the 8025 compact version and the 8035, 115/230 V Ac, without
relays, with cable glands
→
Before wiring the device, configure the selector on the electronic board (see chap. "8.3").
The red wire is wired on the NC terminal to make the wiring of the
4-20 mA output easier (see "Fig. 34"). The jumper wire 4 between L+ and
NC energizes the NC terminal.
