• Power supply voltage polarity is critical. Incorrect voltage polarity can
damage the equipment. Identify the negative (or ground) lead by the
ridges on the side of the cord (see the figure above).
•
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 to 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 AV 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.
• The ideal length of exposed wire in the stripping process is 3/16 inch (5 mm). If
longer than 3/16 inch, the exposed wires may touch, causing a short circuit. If
shorter than 3/16 inch, the wires can be easily pulled out even if tightly fastened.
• Do not tin the wires. Tinned wire does not hold its shape and comes loose
over time.
Connect the AC power cord of the power supply unit to a 110 or 220 VAC electrical
source. When the unit is receiving power, the front panel LED shows a green light.
