Power Supply Wiring
Figure 9 below shows how to wire the connector.
CAUTION: Power supply voltage polarity is critical. Incorrect voltage polarity can
damage the power supply and the transmitter or receiver. Identify the power
cord negative lead by the ridges on the side of the cord.
To verify the polarity before connection, plug in the power supply with no load and check
the output with a voltmeter.

WARNING: The two power cord wires must be kept separate while the power supply is
plugged in. Disconnect the power before wiring.
CAUTION: • This product is intended to be supplied by a Listed Power Unit marked
"Class 2" or "LPS", rated 12 VDC, maximum 1.0 A. Always use a power
supply supplied or specified by Extron. Use of an unauthorized power
supply voids all regulatory compliance certification and may cause damage
to the supply and the end product.
• Unless otherwise stated, the AC/DC adapters are not suitable for use in
air handling spaces or in wall cavities. The power supply is to be located
within the same vicinity as the Extron A/V processing equipment in an
ordinary location, Pollution Degree 2, secured to the equipment rack
within the dedicated closet, podium, or desk.
• The installation must always be in accordance with the applicable
provisions of National Electrical Code ANSI/NFPA 70, article 75, and the
Canadian Electrical Code part 1, section 16. The power supply shall not be
permanently fixed to building structure or similar structure.
NOTES: • 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.
• 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.
• The length of the exposed (stripped) copper wires is important. The ideal
length is 3/16 inches (5 mm). Longer bare wires can short together. Shorter
wires are not as secure in the connector and could be pulled out.
