5.2.6 - Selecting the Reversal Switch polarity

To change the Reversal Switch polarity, simply click on the polarity control toggle.
The Reversal Switch will then inhibit the DC Power Supply’s output, wait for the
voltage to drop to a safe level, change polarity and then re-enable the DC Power
Supply’s output.

The switching time will depend on the configuration of the load. Switching
times may approach 20 seconds.
