Power connection

One power supply can power up to five daisy chained switchers. Additional switchers require one or more power supplies. See "Daisy chain configuration", later in this chapter.

Figure 2-12 shows how to wire the power connector.

CThe two power cord wires must be kept separate while the power supply is plugged in. Remove power before wiring.

CWhen you are connecting the power supply, voltage polarity is critical. Applying power with incorrect voltage polarity could damage the power supply and the VSW 2VGA A. Identify the power cord negative (ground) lead by the ridges on the side of the cord or a black heat shrink wrapping around it.

NStrip the jacket to expose 3/16 inch (5 mm) of the conductors. 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.

To verify the polarity before connection, check the no load power supply output with a voltmeter.

NThe maximum number of switchers that can be daisy chained is limited by several factors: power consumption, cable lengths, and the overall distortion of the video and audio signals.
