  Power connector — Plug the external 12 VDC power supply 
into this 2-pin, 3.5 mm captive screw connector.
Wiring the Power Connector
To wire the connector for the external power supply, 
1.  Cut the DC output cord to the length needed.
2.  Strip the jacket to expose 0.2 inches (5 mm) of the 
conductors. 
C
  Exposing more than 0.2" (5 mm) of the copper 
wires could allow the stripped wires to touch each 
other, causing a short circuit. This could result in 
the external DC power supply overheating and/or 
burning.
Stripping the wires to expose less than the 
recommended amount may cause them to slide out 
of the connector too easily, even if they are tightly 
pinched by the captive screws.
3.  Slide the leads into the supplied 2-pin captive screw plug 
and secure them, using an Extron Tweeker or other small 
screwdriver.
4.  Use the supplied tie wrap to strap the power cord to the 
extended tail of the connector.
5.  To verify the power cord’s polarity before connecting 
it, plug in the power supply with no load and check the 
output with a voltmeter.
Figure 2-12 shows how to wire the connector.

10.  Secure the L-shaped bracket to the square U-bolt using the 
included hex nuts, washers, and lock washers. Tighten the 
hex nuts securely.
N
  Be sure to tighten the hex nuts securely enough that the 
PMK 350 does not slide down the ceiling pole. A socket 
wrench is recommended to tighten the hex nuts. 
11.  Secure the front panel to the mounting tray with four of 
the included #6 screws.
12.  If desired, choose one of the provided four sizes of self-
adhesive cover sheets, and apply it to the underside of the 
mounting tray.
