
Attach a surge device to prevent damage to this product as a result of a lightning-induced power
surge from a large electromagnetic field generated from a direct lightning strike. We also
strongly recommend to connect the crossover grounding wire of this product to a position close
to the ground terminal of the surge protection device.
It is expected that there will be an effect on this product due to fluctuations in grounding potential
when there is a large surge flow of electrical energy to the lightning rod ground at the time of a
lightning strike. Provide adequate distance between the lightning rod grounding point and the
surge protection device grounding point.

If the voltage variation is outside the prescribed range, connect a regulated power supply.
