3.2.4 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.
• Conversely, depending on your environment, grounding may cause a
problem.
• 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.
