(2) Noise Filter Installation
When noise filters are installed to prevent noise from the power line, the block type must be
used. The recommended noise filter is shown in Table A7. 1 The power supply to peripher-
als also needs noise filters.
NOTE
If the noise filter connection is wrong, the effect decreases greatly.
Observing the precautions, carefully connect them as shown in Figs.
A7.2 to A7. 5.
