8.1 Generic Specifications
8.1 Generic Specifications
*1. The criterion is shown in IEC61131-2.
*2. Ground the PLC independently or jointly.
→ Refer to Section 9.4.
*3. For more information on the dielectric withstand voltage test and the insulation resistance test of the
terminals of each product, refer to the following subsection.
→ Refer to Subsection 4.1.1.
*4. Do not use the PLC under pressure higher than the atmospheric pressure. Doing so may damage the
PLC.
