CAUTION

When connecting the power supply, voltage

polarity is extremely important. Applying power with incorrect voltage polarity could damage the power supply and the RAC 104. Identify the power cord negative (ground) lead by the ridges on the side of the cord or a black heat shrink wrapping around it.

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

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