Power connector — Plug the external 12 VDC power supply into this 2-pole, 3.5 mm
captive screw connector. The power supply is included with the unit.
If power is disconnected from the MSW, the unit retains mode and input settings.
CAUTIONS:
• Always use a power supply supplied by or specified by Extron. Use of an
unauthorized power supply voids all regulatory compliance certification
and may cause damage to the supply and the end product.
• Unless otherwise stated, the AC/DC adapters are not suitable for use in
air handling spaces or in wall cavities. The power supply is to be located
within the same vicinity as the Extron A/V processing equipment in an
ordinary location, Pollution Degree 2, secured to the equipment rack
within the dedicated closet, podium or desk.
• The installation must always be in accordance with the applicable
provisions of National Electrical Code ANSI/NFPA 70, article 75 and the
Canadian Electrical Code part 1, section 16. The power supply shall not be
permanently fixed to building structure or similar structure.
To wire the connector, do the following:
1.
Cut the DC output cord to the length needed.
2.
Strip the jacket to expose 3/16 inch (5 mm) of the conductors.

NOTES: • The power connector on the rear panel is orange; however, the plug for
the provided power cord may be either orange or blue. Either color plug
can be connected to the rear panel receptacle.
• The length of the exposed wires in the stripping process is critical. The
ideal length is 3/16 inches (5 mm). Any longer and the exposed wires
may touch, causing a short circuit between them. Any shorter and the
wires can be easily pulled out even if tightly fastened by the captive
screws.
• Do not tin the wires. Tinned wire does not hold its shape and can
become loose over time.
3.
Slide the leads into the supplied captive screw plug and secure them using a small
screwdriver.
