Wiring Requirements

WARNING

Safety First!

Be sure to disconnect the power cord before installing and/or

wiring your M

oxa AWK-1121.

WARNING

Safety First!

Calculate the maximum possible current in each power wire and

common wire. Observe all electrical codes dictating 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.

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.

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 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

when necessary.
