Wiring Requirements
ATTENTION
Be sure to disconnect the power cord before installing and/or wiring your Moxa VPort 25.
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:
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. 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.
