REGISTERS NOT MOUNTED DIRECTLY TO THE METER
In typical LectroCount installations where the LectroCount register is mounted directly to the meter, the LectroCount
LectroCount housing is grounded properly.

1 ohm). Use a 12ga. or larger stranded wire.
FIXED INSTALLATIONS
require metal conduit to the conduit hubs for the wiring. The metal conduit provides the necessary ESD protection.
Divison 2 installations can ground the LectroCount housing by using shielded cables (or wiring) run through liquidtite
installations require and additional grounding method to ensure a proper ground.
1 ohm). Use a 12ga. or larger stranded wire.
Follow this procedure each time you open a LectroCount register or approach a LectroCount register with the door open.
Before opening the LectroCount register and handling the CPU board, it is important to discharge any ESD that may have built up on
your person. To discharge ESD from your person, touch a well-grounded point such as the LectroCount register housing, the meter,
the truck piping, or the bumper. When the maintenance is complete and the LectroCount register door is closed, the CPU board is
protected from ESD by the LectroCount register housing which is grounded to the chassis.
