Wiring Requirements
WARNING
Safety First!
Turn
the power off before disconnecting modules or wires. The
proper
power supply voltage is listed on the product label. Check
the voltage of your power source to make sure you are using the
correct voltage. Do NOT use a voltage greater than
what is
specified on the produc
t label.
These devices must be supplied by a
n
AELV source as defined in
the Low Voltage Directive 2006/95/EC and 2004/108/EC.
WARNING
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 items:
• 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 with similar electrical characteristics can be bundled
together.
• Keep input wiring and output wiring separated.
• We strongly advise labeling the wiring for all devices in the system.
Grounding Your Moxa 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. The
cross sectional area of the ground wires should be at least 3.31 mm
