Always use a power supply specified by Extron Electronics for the DMP 64. Use of
an unauthorized power supply voids all regulatory compliance certification and may
cause damage to the supply and the DMP 64.
When connecting the power supply, voltage polarity is extremely important.
Applying power with incorrect voltage polarity could damage the power supply and
the DMP 64. Identify the power cord negative (ground) lead by the ridges on the
side of the cord or a black heat shrink wrapping around it.
in. Remove power before wiring.
The length of the exposed (stripped) copper wires is important. The ideal length
is 3/16 in (5 mm). Longer bare wires can short together. Shorter wires are not as
secure in the direct insertion connectors and could be pulled out.
Do not tin the stripped power supply leads. Tinned wires are not as secure in the
captive screw connectors and could be pulled out.
