3.12 GROUNDING
In order to avoid any problems with electrical noise that could negatively affect system
function, make sure that:
1. The AC power cable coming into the PWR box is always provided with a Ground and
connected to the proper connector (Protective Earth - PE).
2. The structure where the readers, controllers, encoders/tachometers, and photoelectric
sensors are mounted is grounded to the conveyor or to the PE terminal inside the PWR.
3. The Shield wires from the Encoder/Tachometer and photoelectric sensor cables are
connected to the proper Shield terminal in the CBX box.
4. Normally, steps 1 through 3 will guarantee proper function. In case of problems such as
transmission of strange or wrong characters, devices stop working without any reason, or
other unexpected behavior, try connecting the CBX or Controller Earth terminal to the PE
terminal inside the PWR box.
