4.1. 48 Volt DC Power Option
The 48 Volt DC input is not polarity sensitive. Therefore, you can connect either positive or negative wires from your 48 volt power source to either input and the internal circuitry will adjust for the proper polarity.
Input Range: 40 - 60 Volts DC, 200 milliamps maximum.
