VPort 254 User’s Manual Getting Started
2-16
STEP 2:
Mounting the VPort 254 on the wall requires 4 screws. Use the VPort 254,
with wall mount plates attached, as a guide to mark the correct locations of
the 4 screws. The heads of the screws should be less than 6.0 mm in
diameter, and the shafts should be less than 3.5 mm in diameter, as shown in
the figure at the right.
Do not screw the screws in all the way—leave a space of about 2 mm to
allow room for sliding the wall mount panel between the wall and the
screws.
6.0 mm
3.5 mm
NOTE
Before you mount the unit on the wall, make sure that the screws are the right size by testing
them with the apertures on the mounting plates.
STEP 3:
Once the screws are fixed in the wall, insert the
four screw heads through the large parts of the
keyhole-shaped apertures, and then slide VPort
254 downwards, as indicated in the figure.
Tighten the four screws for added stability.
Wiring Requirements
ATTENTION
Be sure to disconnect the power cord before installing and/or wiring your Moxa VPort 254.
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.
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.
