Power and ground
Each has a ground lug for connection to earth (chassis) ground and a green connector for attachment to a power source (see Ground lug and power connectors on the AVW200).
NOTE:
Only connect the ground lug to earth ground when the is not directly connected to the data logger. When a data logger is in the same enclosure, only connect the data logger ground lug to earth ground.
The ground lug is connected to earth ground using an 8 AWG wire. This connection should be as short as possible.
The power cable terminates in pigtails that attach to the 12V and G terminals on the and the power source. The is often powered by the data logger, but another 12 VDC power source may be used.
