2.2.2 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
• For grounding purposes, use wires with a minimum of 2 mm
2
. The grounding connection should have
a resistance of less than 100 Ω.
• 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.
