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.
Be sure to tighten the hex nuts securely enough that the
N
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.

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.
Exposing more than 0.2" (5 mm) of the copper
C
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.
