Test Item
*2
Measure the emission released by
the product.
*2
Measure the emission released by
the product to the power line.
*2
Immunity test by applying static
electricity to the device enclosure.
Immunity test by applying burst
*2
noise to the power line and signal
line.
Immunity test in which a damped
*2
oscillatory wave is superimposed on
the power line.
*2
Immunity test by applying aradiated
electric field to the product.
Immunity test by inducting an
*2
electromagnetic field in the power
line and signal line.
*1 QP: Quasi-peak value, Mean : Average value
*2 The programmable controller 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 programmable controller was installed inside the control panel.
