CAUTIONS: • When you are connecting the power supply, voltage polarity is extremely
important. Applying power with incorrect voltage polarity could damage
the power supply and the regenerator. Identify the negative lead by the
ridges on the side of the cord (see
connection, plug in the power supply with no load and check the output
with a voltmeter.
• Do not tin the stripped power supply leads before attaching the captive
screw connector. Tinned wires are not secure in the captive screw
connectors and could be pulled out. They may also break after being
bent several times.
• Do not permanently fix the power supply to the building structure or
similar structures.
• Do not place the power supply 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 within the same vicinity as the Extron
AV processing equipment in an ordinary location, pollution Degree 2, and
secured to a podium, a desk, or an equipment rack within a dedicated
closet.
• Always use a power supply specified by Extron for an SW USB. Use of an
unauthorized power supply voids all regulatory compliance certification
and may cause damage to the power supply and the unit.
