Extron Electronics MLA VC10 Plus User Guide - Manual (Page 17)

Connections to a Power Supply
NOTE: During configuration, the host PC provides power through the USB cable.
This is sufficient to power the unit during configuration only. During normal
operation, the unit must receive power from a 12 VDC power supply.
Connect a 12 VDC, power supply to this two pole captive screw connector. Ensure the
connections have the correct polarity (see figure 6).
NOTES: • 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.
• Do not tin the wires. Tinned wire does not hold its shape and can become
loose over time.
The MLA VC10 Plus can be wired to share power with an Extron MLC or IP Link control
processor (see page 12). If it is used with a third party control processor, it must be
connected to a separate 12 VDC, power supply. Read the
attention points below for
important information about connecting the MLA VC10 Plus to a power supply.

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.
• 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, 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.
• Do not use the power supply to power a third party controller jointly
with the MLA VC10 Plus. For the power requirements of the third-
party control system, see the appropriate user guide.
