3 INSTALLATION
3.3.14 Electrical wiring of transmitter 8025, wall-mounted, 12-30 VDC,
with relay
Before wiring the device, please read § 3.3.1, 3.3.3, 3.3.4 and 3.3.11 care-
fully.
Install the device as described in § 3.2.3. Unscrew the 4 screws of the cover and unscrew
the cable glands. Pass the cables through the cable glands by preferably respecting the
allocation indicated in § 3.3.12.
Connect the terminals according to the pin assignment described below.
- Only manipulate the switch when device is not powered.
- Make sure switch "FLOW SENSOR" is correctly positioned
according to the separate sensor version (see § 3.3.4).

PLC
Connections of the 4-20 mA output and of the pulse output (in NPN or PNP mode wiring)
of the wall-mounted transmitter, 12-30 VDC, with relays are similar to these of the compact
transmitter, 12-30 VDC, with relays and cable glands (see Fig. 3.9 in § 3.3.6).
