7-4-1 Circuit protector

When installing a circuit protector dedicated for the control power input, use a circuit protector with
inertial delay to prevent malfunctioning in respect to the rush current generated when the power is
turned ON. The size and conductivity time of the rush current fluctuate according to the power supply
impedance and potential.
