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.
