WARNING
This equipment has been evaluated as EEx nC IIC T4 equipment
under DEMKO Certificate No. 03 ATEX 0324537U. Each module
is marked
II 3G and is suitable for use in Zone 2 Explosive
Atmospheres. The device must be installed in a minimum IP 54
enclosure as defined in IEC 60529 and EN 60529.
WARNING
This unit is a built-in type. When the unit is installed in another
piece of equipment, the equipment enclosing the unit must
comply with fire enclosure regulation IEC 60950/EN60950 (or
similar regulation).
WARNING
Safety First!
Be sure to disconnect the power cord before installing and/or
wiring your MOXA EtherDevice Switch.
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 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.
y 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 MOXA EtherDevice Switch
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.
