			Power supply voltage polarity is critical. Incorrect
	CAUTION
			voltage polarity can damage the power supply and

the MKP. Identify the power cord negative lead by the ridges on the side of the cord (figure 2-12).

To verify the polarity before connection, plug in the power supply with no load and check the output with a voltmeter.

CAUTION	The length of the exposed (stripped) copper wires is
	important. The ideal length is 0.2" (5 mm).
	Longer bare wires can short together. Shorter wires
	are not as secure in the direct insertion connectors
	and could be pulled out.

Do not tin the power supply leads before installing in the direct insertion connector. Tinned wires are not as secure in the connectors and could be pulled out.

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

Alternatively, an Extron P/S 100 Universal 12 VDC Power Supply, part #60-357-01, can power up to ten Extron 12 VDC devices using only one AC power connector.
