Electrical noise generated by other devices might cause failure. When you plan the
power supply, consider the following to enhance anti-noise capability.
Do not connect a foreign device to the branch circuit for this router, especially a
device that switches on/off repeatedly (e.g., an airconditioner) with a relay or
microswitch.

used exclusively for this device.
Anti-electric-noise circuit must be installed in the device generating the electrical
noise.
Two types of cables, power cables and signal cables, are connected to the router.
Since their electric characteristics are different, do not tie or bundle these cables
together when routing.
When a communication line is routed inside the building, do not route it along
the power supply section (including the power cable).
This router includes a noise filter to prevent failure caused by electrical noise. As
a result, a ground current of up to 3.5 mA per device goes through the ground.
Make sure you are obligated to set up the leakage circuit breaker by local laws or
regulations.
