Grounding the Moxa
AWK-3121B
Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI). Run the ground connection from
the ground screw to the grounding surface prior to connecting devices.
Connecting the Power Supplies
The
AWK-3121B s
upports two types of power supplies— PWR1 and
PWR2. The 4-pin male M12 A-coded connector on the
AWK-3121B
front
panel is used for the dual power inputs. You can use the metal M12
male 4-pin A-coded screw-type crimp circular connector with pins for
power connection included with the product or purchase the
M12 power cable (optional) CBL-M12(FF4P)/Open-BK-100-IP68 for lab
use/tests.
Pinouts for the power input (4-pin male M12 A-coded) port:
