Campbell Scientific TORO® NW8002 Weather Station Installation - Manual (Page 5)

I-1
INTRODUCTION
This manual covers both the NW8002AC (115 VAC power only) and the NW8002SP (solar panel)
weather stations. These weather stations are setup to communicate with the NW8000 central computer
over a short haul modem link. The heart of the weather station is the Campbell Scientific, Inc. CR10
Measurement and Control Module. A 2.5 amp hour 12 VDC sealed lead acid battery pack powers the
CR10. A solar panel or 115 VAC power is used to trickle charge the batteries.

NOTE: The black outer jacket of the cables
is Santoprene
®
rubber. This compound was
chosen for its resistance to temperature
extremes, moisture, and UV degradation.
However, this jacket will support
combustion in air. It is rated as slow
burning when tested according to U.L. 94
H.B. and will pass FMVSS302. Local fire
codes may preclude its use inside buildings.
