CONNECTING GROUND WIRES
Both the OSU and the NIM box must be grounded to a grounding
rod in the earth near your house. Make sure your grounding rod does
not exceed a 50 feet maximum.
To ground the NIM box and the OSU:
1 Inside the NIM box, unscrew the hex nut labelled GND.
2 Insert one end of the grounding wire through the rubber
grommet on the bottom of the NIM box.
3 Loop the grounding wire around the ground post.
4 Re-tighten the hex nut around the wire to hold it in place.
5 Connect the other end of the grounding wire to the grounding
rod in the ground next to the house.
