MTP AV Series • Installation 12
ATTENTION:
• Power supply voltage polarity is critical. Incorrect voltage polarity can damage the
power supply and the MTP. Identify the power cord negative lead by the ridges on
the side of the cord (see
figure 15).
• The length of the exposed (stripped) copper wires is important. The ideal length
is 3/16 inches (5 mm). Longer bare wires can short together. Shorter wires are
not as secure in the captive screw connectors and could be pulled out.
To verify the polarity before connection, plug in the power supply with no load and
check the output with a voltmeter.
Use the supplied tie-wrap to strap the power cord to the extended tail of the connector.
NOTES:
• Your transmitter/receiver pair may have shipped with a blue captive screw
connector. This blue connector can be plugged into either a blue or an orange
power receptacle.
• The blue connector does not have an extended tail or the included tie-wrap.
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.
b Power LED — Indicates power is applied to the MTP.
