You should also pay attention to the following items:

y Use separate paths to route wiring for power and devices. If power wiring

and device wiring paths must cross, make sure the wires are perpendicular

at the intersection point.

NOTE: Do not run signal or communications wiring and power wiring in

the same wire conduit. To avoid interference, wires with different signal

characteristics should be routed separately.

y You can use the type of signal transmitted through a wire to determine

which wires should be kept separate. The rule of thumb is that wiring with

similar electrical characteristics can be bundled together.

y Keep input wiring and output wiring separate.

y It is strongly advised that you label wiring to all devices in the system when

necessary.

Grounding Moxa AWK-6222

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.

ATTENTION

This product is intended to be mounted to a well-grounded

mounting surface, such as a metal panel. There must be no

potential difference between two ground potentials, otherwise

there is a risk that the device could be destroyed.

Wiring the Redundant Power Inputs

The AWK-6222 must be connected to a power-over-Ethernet (PoE) IEEE

802.3af compliant power source or an IEC60950 compliant limited power

source. When AWK-6222 is powered via DC power, the M12 A-coding

connector on the bottom panel is used for the AWK-6222’s two redundant

inputs. The pin assignment is shown below:

2 V2+

3 V1-

4 V2-
