• This product is intended to be supplied by a Listed Power Unit marked
"Class 2" or "LPS", rated 12 VDC, maximum 1.0 A. Always use a power
supply supplied 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.
• Your transmitter/receiver pair may have shipped with a blue captive screw
connector. This blue connector can be plugged into either a blue or an orange
power receptacle. The blue connector does not have the extended tail or the
included tie-wrap.
•
Do not tin the power supply leads before installing in the direct insertion
connector. Tinned wires are not as secure in the connectors and could be
pulled out of the connector.
• The length of the exposed (stripped) copper wires is important. The ideal
length is 3/16 inches (5 mm). Longer bare wires can short together. Shorter
wires are not as secure in the connector and could be pulled out.
