CAUTION
1 Ground the shield of the cable drawn from the
outside of the cabinet to the ground plate provided
near the cabinet inlet with a clamp. This is to
prevent noise on the cable shield outside the
cabinet from getting into the cabinet and also to
prevent noise inside the cabinet from radiating
outside.
2 Connect the FG terminal of the βi SVM to a ground.
Use a Faston terminal (A65L-0001-0148/2) as the
terminal on the βi SVM side. Use a 2-mm
2
or
thicker twisted cable with a length of around 100 to
300 mm for installation. If the FG terminal is not
grounded as mentioned here, the unit becomes
more susceptible to noise.
3 The flange of the βi SVM has an M4 threaded hole
for grounding. Use this hole for grounding as
shown in the above figure.
