ATTENTION: • 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.
NOTES:
• The ideal length of exposed wire in the stripping process is 3/16 inch (5mm).
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.
2. 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.
