Wiring
When wiring, observe the terminal labels on the
mounting base. Maximum wire size is 2 mm
2
(AWG14).
The RS-485 line of the transmitter is isolated from the
power supply. A separate ground reference terminal
(
) is provided for the RS-485 connection.
If you are using a shielded cable, you can use the
terminal to hold the exposed part of the shield. The
Shld terminal is floating (not electrically connected).
