Ma
ke sure the external power adapter (includes power cords
and plug assemblies) provided with the unit is certified and
suitable for use in your country.
• Yo
u
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 with similar electrical characteristics can be bundled
together.
• Keep input wiring and output wiring separate.
• It is strongly advised that you label wiring to all devices in the
system for easy identification.
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.
Wiring Requirements
You
should also pay attention to the following items:
• 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.

Saf
ety First!
Calculate the maximum possible current in each power wire
and common wire. Observe all electrical codes that dictate
the maximum current allowed for each wire size.
If the current goes above the maximum ratings, the wiring
could overheat, causing serious damage to your equipment.
WARNING
Safety First!
Be sure to disconnect the power cord before installing and/or
wiring your AWK-3121B.
