It is quite important to ground an electric or electronic instrument.
The purposes of grounding are as shown below:
(1) Preventing damages to the instrument caused by charging of the metallic
casing originating from deterioration or defects of insulating material of the
electrical circuits of the instrument.
(2) Preventing electrostatic hazards caused by static electricity in the instrument.
(3) Eliminating noises by equalizing the potential levels of the instrument casing
and ground.
(4) Preventing lightning damages.
This instrument requires class D grounding.
Class D grounding prevents electric shocks or electrocution in the case where
electric current leaks from an instrument whose source voltage is 300 VAC or less.
The class D grounding resistance must obligatorily be 100 ohms or less.
Exclusive grounding work should desirably be carried out in conformity to the
electric facility technical standards.
