EMC AND LOW VOLTAGE DIRECTIVES
(2) Power supply module
The precautions required for each power supply module are described in Table9.4.
Always observe the items noted as precautions.
* 1: If sufficient filter circuitry is built into the 24VDC external power supply module, the noise
generated by A1S63P will be absorbed by that filter circuit, so a line filter may not be required.
Filtering circuitry of version F or later of A1S63P is improved so that a external line filter is not
required.
