3.2.2 Grounding
Be sure to ground when the influence of noise is great
The unit is tolerant against noise in normal environments, but if the environment is particularly
susceptible to noise, please ground.
Use dedicated grounding
Make the grounding point as close as possible to the GT and keep the distance of the grounding wire
short.
Sharing the ground with another device may have an adverse effect. Therefore, be sure that grounding
is dedicated.
Note:
Conversely, depending on your environment, grounding may cause a problem.
Example:
Since the power line of the GT unit is connected to a functional earth via electronic parts, the electronic
parts may become damaged if there is an abnormal potential between the power line and the physical
ground.
Do not ground the function earth when grounding a plus (+) terminal of the power. (GT01, GT11,
GT21)
In some computers, the SG terminal of RS232C port and connector shielding are connected. Also the
tool port shielding is connected with the function earth terminal. Therefore, the GND terminal and the
function earth terminal are connected if the computer is connected. Especially when the GT is connected
to a computer with a plus (+) terminal grounded, therefore, an GT
’s minus (-) terminal is connected with
the function earth terminal. As a result, short circuit occurs which may lead to the breakage of GT and its
neighboring parts.
