Connecting Power

The RUGGEDCOM i802 supports a single low DC power supply with reverse polarity and dual independent
inputs. This allows for two redundant DC power sources with the same nominal voltage to be connected.
To connect power to the device, do the following:
IMPORTANT!
• Terminals P1-, P2- and GND are connected together internally. As such, if redundant power supplies
are connected, their negative terminals must be at the same potential.
• Do not field wire the DC power supply on the DC mains or Battery mains.
• Use only #16 gage wiring when connecting terminal blocks.
• Equipment must be installed according to applicable local wiring codes and standards.
1.
Connect the positive wire from the power source to the positive terminal (P1+ or P2+) on the terminal block.
