Power Connection — Plug the external 12 VDC power supply into this connector. The
power supply is included with the unit.
WARNING: When wiring, the two power cord wires must be kept separate while
the power supply is plugged in. Remove power before continuing.
CAUTION: Always use a power supply supplied by 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 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.
When connecting the power supply, voltage polarity is extremely
important. Applying power with incorrect voltage polarity could
damage the power supply and the unit. Identify the power cord
negative lead by the ridges on the side of the cord.

connectors and could pull out.
To verify the polarity before connection, plug in the power supply with no load and
check the output with a voltmeter.
