The two power cord wires must be kept separate
while the power supply is plugged in. Remove
power before wiring.
C
The length of the exposed (stripped) copper wires
is important. The ideal length is 3/16" (5 mm).
Longer bare wires can short together. Shorter wires
are not as secure in the connector and could be
pulled out.
N
Do not tin the power supply leads before installing in
the direct insertion connector. Tinned wires are not as
secure in the connectors and could be pulled out of the
connector.
Non-Decora units only — Use the supplied tie-wrap to strap
the power cord to the extended tail of the connector.

Your transmitter/receiver pair may have shipped with a
blue captive screw connector. This blue connector can be
plugged into either a blue or an orange power receptacle.
The blue connector does not have the extended tail or the
included tie-wrap.
Snap the provided ferrite bead onto the DC power cable,
between the power supply and the HDMI unit’s connector.
