NOTE Test the screw head and shank size by inserting the screw into one
of the keyhole shaped apertures of the Wall Mounting Plates,
before it is screwed into the wall.
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 AWK-3121
downwards, as indicated below. Tighten the four screws for added stability.
Wiring Requirements
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or
wiring your MOXA AWK-3121.
ATTENTION 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 points:
§ 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 that shares
similar electrical characteristics can be bundled together.
§ Keep input wiring and output wiring separated.
§ It is strongly advised that you label wiring to all devices in the system when
necessary.
