Extron Electronics SCP 104 Series User Guide - Manual (Page 18)

Wiring the Power Connector (Optional)
If powering the SCP using a 12 V, 1 A external power supply
(instead of powering via an MLC or System 5 IP), connect the
power supply to ports A and B of either 5-pole captive screw
connector on the SCP rear panel. Connect the + wire to port A
and the ground wire to port B, as shown in the figures below.

Figure 9. Connecting the Power Supply
WARNING:
Risk of electric shock. The two power cord wires
must be kept separate while the power supply is
plugged in. Remove power before continuing.
To verify the polarity before connection, plug in the power
supply with no load and check the output with a voltmeter.
ATTENTION:
• When you are connecting the power supply,
voltage polarity is extremely important.
Applying power with incorrect voltage polarity
could damage the power supply and the
equalizer. Identify the negative lead by the
ridges on the side of the cord (see figure 8,
above).
• Do not tin the stripped power supply leads
before installing the captive screw connector.
Tinned wires are not as secure in the captive
screw connectors and could be pulled out.
