PRECAUTIONS FOR USE OF THE CONVERTER UNIT

Data line filter
Data line filter is effective as an EMI countermeasure. Provide a data line filter for the detector cable, etc.
<Example> Data line filter : ZCAT3035-1330 (by TDK)
: ESD-SR-250 (by NEC TOKIN)
Impedance (ZCAT3035-1330)
The impedance values above are reference values,
and not guaranteed values.
