Hardware Arrangement
The coils and contacts in electromagnetic contacts and relays in an external circuit are sources of
noise. Do not install them close to the AMR Controller. Locate them at least 100 mm away from the
AMR Controller.

Wire Layout for the Power Supply
Observe the following points when wiring the power supply system.
• Separate the AMR Controller power supply from the I/O device power supply and install a noise filter
near the AMR Controller power supply feed section.
• Use an isolating transformer to significantly reduce noise between the AMR Controller and the
ground. Install the isolating transformer between the AMR Controller power supply and the noise fil-
ter, and do not ground the secondary coil of the transformer.
• Keep the wiring between the transformer and the AMR Controller as short as possible, twist the
wires well, and keep the wiring separate from high-voltage and power lines.
