Extron electronic MTP manual Receiver output connections, Important. The ideal length is 3/16 5 mm

Installation, cont’d

If the transmitter and receiver are either older generation units or jumper configured to the stereo audio position (compatible with the older units), only a single device needs to be powered in a two-unit system. See “Signal Jumpers for Generational Compatibility” on page 2-2. The device connected to the power supply, in turn, provides power to its counterpart.

If the transmitter and receiver are separated by greater than 500 feet (150 meters) of STP/UTP/FTP cable, connect a power supply to both units regardless of the model and jumper configuration.

CAUTION	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 (figure 2-19).
	The length of the exposed (stripped) copper wires is
CAUTION
	important. The ideal length is 3/16" (5 mm).
	Longer bare wires can short together. Shorter wires
	are not as secure in the captive screw connectors
	and could be pulled out.

Do not tin the stripped power supply leads before installing the captive screw or direct insertion connector. Tinned wires are not as secure in the captive screw and direct insertion 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.

The two power cord wires must be kept separate while the power supply is plugged in. Remove power before wiring.

Use the supplied tie-wrap to strap the power cord to the extended tail of the connector.

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 the extended tail or the included tie-wrap.

Alternatively, 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.
