*2 The PLC is an open type device (device installed to another device) and must be installed in a
conductive control panel.The tests for the corresponding items were performed while the PLC
was installed inside the control panel.
Test Description
Measure the emission released by
the product.
Measure the emission released by
the product to the power line.
Immunity test by applying static
electricity to the module enclosure.
Immunity test by applying burst
noise to the power line and signal
line.
Immunity test in which damped
oscillatory waves are applied to
power line.
Immunity test in which electric fields
are applied to the product.
Immunity test in which
electromagnetic fields are induced to
power cables and signal line.
