3-1-4 Grounding
The NT31/NT31C has a functional ground terminal ( ).
Carry out wiring under the following conditions.
1,2,3... 1. In cases where there is a potential difference between the grounds of the
NT31/NT31C and the host, ground as shown in the following figure. If there
is some distance between the NT31/NT31C and host and grounding at a
single point is difficult, do not connect the functional ground terminal ( )
of the NT31/NT31C.
2. If the NT31/NT31C is installed in the same panel as equipment that gen-
erates noise, such as a motor or inverter, do not ground the functional
ground terminal ( ) of the NT31/NT31C.
Note Carry out grounding correctly in order to prevent operating errors due to
noise.
