Dielectric withstand voltage test and insulation resistance test
Perform dielectric withstand voltage test and insulation resistance test at the following voltages between each terminal and
the CPU module ground terminal.
■
CPU module, I/O module
■
Expansion board, expansion adapter
For dielectric withstand voltage test and insulation resistance test of each product, refer to manuals of each product.
■
Intelligent function module
For information concerning dielectric withstand voltage and insulation resistance of intelligent function modules, refer to
manuals of each intelligent function module.
