9. Move the PMK 350 up to the desired location on the ceiling pole, as close to the ceiling as desired.

10. Secure the L bracket to the U-bolt, using the included hex nuts. Hand-tighten the hex nuts, make any final adjustments to the PMK’s position, then tighten the hex nuts securely, using an 11/16" deep socket or box-end ratchet wrench.

NBe sure to tighten the hex nuts securely enough that the PMK 350 does not slide down the ceiling pole.

11. Secure the front panel to the mounting tray with four of the included #6 screws.

12. If desired, tear out one of the four perforated self-adhesive overlay sheets, and apply it to the underside of the mounting tray.

MDA 4SV EQ rear panel

1Power connector — Plug the external 12 VDC power supply into this 2-pin, 3.5 mm captive screw connector. The power supply is included with the unit.

The power connector on the rear panel is orange; however, the plug for the power cord may be either orange or blue. Either color plug can be connected to the rear panel receptacle.

To wire the connector:

1. Cut the DC output cord to the length needed.

2. Strip the jacket to expose 0.2" (5 mm) of the conductors for the blue captive screw plug, or 0.3" (7 mm) for the orange plug.

WExposing more than the amount of copper wire described above 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.

NStripping the wires to expose less than the recommended amount causes 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 captive screw plug and lock them, using an Extron Tweeker (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.
