Power supply wiring

ATTENTION: Always use power supplies specified by Extron for the FOXBOX units.
Use of an unauthorized power supply voids all regulatory compliance
certification and may cause damage to the supply and the unit.
Figure 10 shows how to wire the power connector.

ATTENTION:
• This product is intended to be supplied by a Listed Power Unit marked
"Class 2" or "LPS," rated 12 VDC, 1.0 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 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.
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 the exposed (stripped) copper wires is important. The ideal
length is 3/16 inch (5 mm) (see the second RS-232 Connections
on page 8 for more information).
NOTE:
Do not tin the power supply leads before installing them in the captive screw
connector. Tinned wires are not as secure in the connectors and could be pulled
out.
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, part number
60-1022-01, can power multiple Extron 12 VDC devices using only one AC power connector.
