Wiring Requirements

WARNING

Do not disconnect modules or wires unless power has been

switched off or the area is known to be non-hazardous. The devices

may only be connected to the supply voltage shown on the type

plate.

These devices must be supplied by a SELV source as defined in the

Low Voltage Directive 2006/95/EC and 2004/108/EC.

ATTENTION

Safety First!

Be sure to disconnect the power cord before installing and/or

wiring your Moxa Industrial Media Converter.

This equipment is approved by UL508. Use copper conductors

only, 60/75°C, and tighten to 4.5 pound-inches.

ATTENTION

Safety First!

Calculate the maximum possible current in each power wire and

common wire. Observe all electrical codes dictating the maximum

current allowable for each wire size. If the current goes above the

maximum ratings, the wiring could overheat, causing serious

damage to your equipment.

You should also pay attention to the following points:

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 that

shares similar electrical characteristics can be bundled together.

y Keep input wiring and output wiring separated.

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

necessary.

Grounding the IMC-101G

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.
