Wiring Requirements
WARNING
Do not disconnect modules or wires unless the power supply has
been switched off or the area is known to be non-hazardous. The
devices may only be connected to the supply voltage shown on
the type plate. The devices are designed for operation with a
Safety Extra-Low Voltage. Thus, they may only be connected to
the supply voltage connections and to the signal contact with the
Safety Extra-Low Voltages (SELV) in compliance with IEC
60950-1/EN 60950-1.

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 60950-1/EN60950-1
(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.
