5-4-4. Functional Earth Connection
The F3SG-SR operates properly without functional earth connection in a general industrial
environment. If the F3SG-SR fails due to electrical noise, connecting the F3SG-SR to the functional
earth may work to prevent the noise. It is recommended the functional earth terminal of the F3SG-SR
be connected to functional earth cables. Connection with protective earth cables may cause the F3SG-
SR to fail due to a noise level of the environment.
When you connect the F3SG-SR with the functional earth, connect an earth cable to the functional
earth terminals, as shown below.
The size of the screws of the terminals is M3. Make sure to use crimp terminals that fits the size.
The earth cable must have a cross section of 1 mm
2
or more with conductor resistance of 0.058 ohms/
m or less and a length of 20 m or less.
