Power connection point — This dedicated female,
3.5mm, 2-pole captive screw connector enables
connection of the 12 VDC external power supply. Wire
the power supply cord into the supplied male orange
connector as shown in figure 2-8.
C Power supply voltage polarity is critical. Incorrect
voltage polarity can damage the power supply and
the SCS 300. Identify the power cord negative lead
by the ridges on the side of the cord (figure 2-8).
C The length of the exposed (stripped) copper wires
is important. The ideal length is 5/16” (7 mm).
Longer bare wires can short together. Shorter wires
are not as secure in the captive screw connectors
and could be pulled out.
N Do not tin the stripped power supply leads before
installing the captive screw connector. Tinned wires are
not as secure in the captive screw connector and could be
pulled out. Use the supplied tie warp to strap the wires to
the connector.
