4.2.4 Grounding

 Ground the instrument to ensure sufficient noise suppression.
 The point of grounding should be as close to the PLC as possible. The ground wire should
be as short as possible.
 Sharing the ground with another device may have an adverse effect. Therefore, be sure that
grounding is dedicated.
 Earth terminals for an AC power supply unit should be grounded at a grounding resistance of
100 Ω or less.
 When 24V DC is directly supplied to the CPU unit, install the attached functional earth
(Green).
