Weidmuller IE-MC-VL Series - Industrial Ethernet Media Converters - Manual (Page 7)

WARNING This equipment has been evaluated as EEx nC IIC T4
equipment under DEMKO Certificate No. 03 ATEX
0324537U. Each module is marked with
II 3G and is
suitable for use in Zone 2 Explosive Atmospheres. Devices
must be installed in a minimum IP 54 enclosure as defined in
IEC 60529 and EN 60529.
ATTENTION This unit is a built-in type. During installation into certain
end equipment, it must comply with fire enclosure
stipulations of IEC 60950/EN60950, or similar statements.
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or
wiring your Weidmüller Media Converter.
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 Media Converter
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.
