of an unauthorized power supply voids all regulatory compliance certification and may
cause damage to the supply and the unit.

ATTENTION:
• This product is intended to be supplied by a Listed Power Unit marked “Class 2”
or “LPS,” rated 12 VDC, 2.0 A minimum. Always use power supplies 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 a
building structure or similar structure.
• Power supply voltage polarity is critical. Incorrect voltage polarity can damage the
power supply and the unit. The ridges on the side of the cord (figure 11) identify the
power cord negative lead.
To verify the polarity before connection, plug in the power supply with no load and check the
output with a voltmeter.
CAUTION: Electric shock hazard — The two power cord wires must be kept
separate while the power supply is plugged in. Remove power before wiring.
ATTENTION: The length of exposed wires is important (see the first two RS-232 and
IR connector NOTES on page 12 for more information).
Use the supplied tie wrap to strap the power cord to the extended tail of the connector.
Alternatively, an optional Extron PS 124 Universal 12 VDC Power Supply can power multiple
Extron 12 VDC devices using only one AC power connector.
