Step 8: Install grounding wire if applicable.
Insert the grounding wire
through the opening and plug it into the ground connector. The grounding
wire is recommended if you are using the Wind Speed and Direction Smart
Sensor (S-WCA-MXXX) or if you are installing the HOBO U30 Station on a
roof or in a location with exposure to lightning. The grounding wire may
also be helpful in reducing sensor errors when installing the HOBO U30
Station near other radio or electrical equipment or antennas.

Step 9: Route the cable for the solar panel or AC adapter through the
opening, but do not connect it yet.
Later in this section you will connect
the battery and then plug in the solar panel or AC adapter. You need to route
the solar panel or AC adapter cable through the opening at this point,
however, so that you can properly install the rubber cable channel.
Step 10: Install the rubber cable channel(s).
All cables and wires should
be routed through the cable access opening at this point. If you are using the
Smart Sensor expander board, make sure those cables are routed through the
secondary cable access opening.

1.
Apply a small amount of silicone grease (about the size of a pea)
onto your fingertip and then work a light coating into the top,
bottom, and two ends (the sides with no holes) of the rubber cable
channel. Also put a light coating on the inside of the two halves of
the cable channel.

2.
Hold the channel just below the HOBO U30 Station case (with the
channel’s hinged side on the left and the taper facing in). Open the
channel and lay the cables and wires into the grooves.
Note:
The
solar panel or AC adapter cable must be in the leftmost (larger
diameter) groove. Use the small rubber plugs to fill any unused
grooves. Center the thick part of the plugs in the groove. Plug ‘tails’
can face in or out.
