Connect the two-pole, 3.5 mm captive screw connector from the power supply to
the power socket on the rear panel of the MPA 152, as shown above. Ensure the
connections have the correct polarity.
ATTENTION:
• 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.
• Suitable for use in environmental air space in accordance with
Section 300.22.C of the National Electrical Code, and Sections 2-128,
12-010(3) and 12-100 of the Canadian Electrical Code, Part 1, C22.1.
• Unless otherwise stated, the AC/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 and the Canadian Electrical Code. The
power supply shall not be permanently fixed to building structure or similar
structure.
• The length of the exposed wires in the stripping process is critical. The ideal
length is 3/16 inches (5 mm). Any longer and the exposed wires may touch,
causing a short circuit between them. Any shorter and the wires can be easily
pulled out even if tightly fastened by the captive screws.
NOTE: Do not tin the wires. Tinned wire does not hold its shape and can become
loose over time.
