Electrical Noise
62
When an inductive load is connected to an I/O Unit, connect a surge suppressor
or diode in parallel with the load as shown in the following diagram. This is so that
the back electromagnetic field generated by the load will be absorbed.
Take appropriate measures when any electrical device likely to produce noise is
connected to the PC as a load. Devices generating noise of more than 1,200 V
(such as electromagnetic relays and valves) require noise suppression. For
noise sources running on AC power, connect a diode in parallel with the coil of
each device.
When mounting a CPU Rack and an Expansion I/O Rack together on a mounting
plate, provide a solid ground to the mounting plate. The mounting plate must be
plated with a highly conductive surface in order to ensure noise immunity.
