When installing or wiring devices, make sure that there will be no danger to people and that noise will
not interfere with electrical signals.
Install the Controller as far away as possible from high-voltage (600 V or higher) and power devices to
ensure safe operation and maintenance.
The coils and contacts in electromagnetic contacts and relays in an external circuit are sources of
noise. Do not install them close to the Controller. Locate them at least 100 mm away from the Control-
ler.
