Connecting the Power Supply

Type and item Power supply voltage
Main power supply: AC200 to 230V ±10%
SRCP30
Controlled power supply: AC200 to 230V ±10%

CAUTION
If the power supply voltage drops below the above range during operation, the alarm circuit will work and return
the SRCP30 controller to the initial state the same as just after power-on, or stop operation. To avoid this
problem, use a regulated power supply with voltage fluctuations of less than ±10%.
Since the SRCP30 controller uses a capacitor input type power supply circuit, a large inrush current flows when
the power is turned on. Do not use fast-blow circuit breakers and fuses. For the same reason, avoid turning the
power off and on again repeatedly in intervals of less than 10 seconds. This could harm the main circuit ele-
ments in the SRCP30 controller.
2-2-2 Connecting the power supply
After making the necessary wiring to the main power connector and control power connector that
came with the controller, connect them to the controller. Make correct connections while referring to
the printed letters and mark. Misconnections may result in serious danger such as fire. Securely
connect the end of each wire to the terminal so that it will not come loose.
