Powerpole Configuration
The Powerpole connectors mounted on the front panel conform to the RACES/ARES standard orientation.

Input Voltage Selection
The power supply is set up for 115V AC input as shipped from the factory. For 230V AC applications, set the recessed 115/230 input select switch located on the rear of the power supply into the proper position. Positions are identified on the switch. Use a small screwdriver to slide the switch into position. No adjustment is necessary for either 50 or 60 Hz input.

The SS-30DV power supply is cooled by convection and forced air cooling (normal airflow around the power supply in combination with a temperature controlled fan to improve cooling at higher levels of use). The fan is activated by a sensor when the temperature rises above 70°C.
