• 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.

• 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.

• 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 that shares similar electrical characteristics can be

bundled together.

• Keep input wiring and output wiring separated.

• We strongly advise that you label wiring to all devices in the system.

Grounding the Moxa IMC

Grounding and wire routing help limit the effects

of noise due to electromagnetic interference

(EMI). Run the ground connection from the right

most

connector of the 3-contact terminal block 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.

Wiring the Power Inputs

The two left-most contacts of the 3-contact terminal block connector on

the IMC’s top panel are used for the IMC’s DC inputs. Take the following

steps to wire the IMC’s DC power inputs:

STEP 1: Insert the negative/positive DC wires

into the V

-/V+ terminals.

STEP 2: To keep the DC wires from pulling loose,

use a small flat

blade screwdriver to tighten the

wire

-clamp screws on the front of the terminal

block connector.

STEP 3:

Insert the plastic terminal block

connector prongs into the terminal block

receptor, which is located on IMC’s top panel.
