This equipment has been evaluated as EEx nC IIC T4 equipment
under DEMKO Certificate No. 03 ATEX 0324537U. Each module
II 3G and is suitable for use in Zone 2 Explosive
Atmospheres. Devices must be installed in a minimum IP54
enclosure as defined in IEC 60529 and EN 60529.
-in type. During installation into certain end
equipment, it must comply with fire enclosure stipulations of IEC
60950/EN60950, or similar statements.
Be sure to disconnect the power cord before installing and/or
wiring your Moxa IMC-101.
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:
• 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.
• 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.
• It is strongly advised that you label wiring to all devices in the system
when necessary.
Grounding the IMC-101
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.
