SW HDMI LC • Installation 5
Wiring the Power Connector (Optional)
A 12 VDC, 1 A desktop power supply with a 2-pin captive screw connector attached is
provided with the SW HDMI LC. If you are using a different external power supply from
the provided one, you may need to wire the captive screw connector for your power
supply.
CAUTIONS: The power supply must not be permanently fixed to the building structure
or similar structures.
The power supply must not be located within environmental air handling
spaces or the wall cavity.
The installation must be in accordance with the applicable provisions of
the National Electrical Code ANSI/NFPA 70, Article 725 and the Canadian
Electrical Code, Part 1, Section 16.
The power supply must be located in the same vicinity as the Extron A/V
processing equipment in an ordinary location, Pollution Degree 2, secured
to a podium, a desk, or an equipment rack within a dedicated closet.
Always use a power supply specified by Extron for the SW HDMI LC.
Use of an unauthorized power supply voids all regulatory compliance
certification and may cause damage to the supply and the switcher.
1. Cut the DC output cord to the length needed.
2. Strip the jacket to expose 3/16 inch (5 mm) of the conductors.
CAUTION: Exposing more than 3/16 inch (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
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 a
small screwdriver.
4. To verify the power cord polarity before connecting the plug, connect in the power
supply with no load and check the output with a voltmeter.
WARNING: The two power cord wires must be kept separate while the power
supply is plugged in. Remove power before wiring.
CAUTION: Do not tin the stripped power supply leads before attaching the
captive screw plug to them. Tinned wires are not as secure in the
captive screw connectors and can be easily pulled out. They may also
break after being bent several times.
