CAUTION: Always use a power supply supplied and 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.
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 10) 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.
WARNING: The two power cord wires must be kept separate while the power supply
is plugged in. Remove power before wiring.
CAUTION: The length of the exposed (stripped) copper wires is important. The
ideal length is 3/16 inch (5 mm). Longer bare wires can short together.
Shorter wires are not as secure in the connectors and could be pulled out.
NOTE: Do not tin the power supply leads before installing them in the direct insertion
connector. Tinned wires are not as secure in the connectors and could be
pulled out.
Rather than the included power supply, you can use an optional Extron PS 123 Universal
12 VDC Power Supply, part #60-814-01, can power multiple Extron 12 VDC devices using
only one AC power connector.
