Tally Out port — (Optional) Plug one of the provided 5-pole captive screw
connectors into this 5-pole captive screw port to indicate which input has been
selected. On the SW6 and SW8 HDMI, plug connectors into either or both parts of
the dual Tally Out port.
Connect an indicator device such as an LED to the attached connector to identify the
currently selected input when the front panel buttons are not visible (see
Tally Out Port to Indicate the Input Selection
separate while the power supply is plugged in. Remove power before wiring.
• 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 AV
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 for the SW HDMI by Extron. Use of an
unauthorized power supply voids all regulatory compliance certification and may
cause damage to the supply and the switcher.
Cut the DC output cord to the length needed.
Strip the jacket to expose 3/16 inch (5 mm) of the conductors.
ATTENTION:
• 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.
• 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.
Slide the leads into the supplied 2-pole captive screw plug and secure them, using a
small screwdriver.
To verify the power cord polarity before connecting the plug, connect the power
supply with no load and check the output with a voltmeter.
