Power Supply
(12 VDC, 1 A )
CAUTION:  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.
NOTES:  The length of the exposed wires in the stripping process is critical.  The ideal length is 
3/16 inches (5 mm).  If the exposed section is longer, the exposed wires may touch, causing a short 
circuit between them. If it is shorter, the wires can be easily pulled out even if tightly fastened by 
the captive screws. 
 
Do not tin the wires.  Tinned wire does not hold its shape and can become loose over time.
Step 4 — Applying Power
NOTE:  Output 1 is used as DDC reference and Hotplug Detect and a local monitor must be 
connected to it before the source device is powered on. Since Output 1 is used for reference, all 
displays connected to the other outputs must be capable of handling resolutions greater than or 
equal to that of Output 1.
