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 14 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 14) 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: 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 RS-232 Connections NOTE 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.
