4.2 Power and Ground

Each AVW200 has a ground lug for connection to earth ground and a green

connector for attachment to a power source (see FIGURE 4-2).

Only connect the AVW200 ground lug to earth ground when the

AVW200 is not directly connected to the datalogger. When a

datalogger is in the same enclosure, only connect the datalogger’s

ground lug to earth ground.

The AVW200’s ground lug is connected to earth ground via an 8 AWG wire.

This connection should be as short as possible.

The 19246 power cable is shipped with each AVW200 for connection to a

power source. The cable terminates in pigtails that attach to the 12V and G

terminals on the AVW200 and the power source. Often the AVW200 is
