Wiring Requirements
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.
Be sure to read and follow these important guidelines:
•
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
through the same wire conduit. To avoid interference, wires with
different signal characteristics should be routed separately.
•
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 separate.
•
When necessary, you should label the wiring to all devices in the
system.
Grounding the 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.
