CAUTION: Power supply voltage polarity is critical. Incorrect voltage polarity
can damage the power supply, the transmitter, the receiver, or both.
Identify the ground ( ) lead by the ridges on the side of the cord
(see the figure above).
NOTE: 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.
Both the transmitter and receiver can be powered by a 12 VDC, 1 A power supplies
connected directly to each unit. In addition, twisted pair cable 2, pin 5 carries a
12 VDC power signal. This remote powering feature allows the receiver to be
powered from a single power supply connected to the transmitter at the other end
of a CAT 5, 5e, or 6 cable or an Extron DTP26 cable.
CAUTION: 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/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 A/V 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.
