CAUTION Power supply voltage polarity is critical. Incorrect
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 (see figure 2-17,
above).
To verify the polarity before connection, plug in the power
supply with no load and check the output with a voltmeter.
The length of the exposed (stripped) copper wires is
important. The ideal length is 3/16" (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 them
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, you can use the optional Extron P/S 123
Universal 12 VDC Power Supply, part #60-814-01, which can
power up to 10 Extron 12 VDC devices using only one AC
power connector.
Mounting the MKP 10 MAAP
The MKP 3000 MAAP has a space that allows the installation of
up to four optional mini architectural adapter plates. This space
is typically filled by an optional four space MKP 10 MAAP
keypad (figure 2-18).

When the connected switcher has a large matrix size (up to 128
by 128) selecting an input or output number by rotating the
Select knob can be inconvenient. The optional MKP 10 MAAP
keypad allows rapid input/output selection.
Mount the MKP 10 MAAP to the MKP 3000 MAAP before
installing the MKP 3000 MAAP, as follows:
The proper MKP 10 MAAP orientation is with the
power LED up.
