• Wire a separate circuit for the power supply circuit so that there is no voltage drop from the inrush
current or startup current that flows when other equipment is turned ON.
• When several CP1E PLCs are being used, it is recommended to wire the PLCs on separate cir-
cuits to prevent a voltage drop from the inrush current or incorrect operation of the circuit breaker.
