SRCP-10A	AC100 to 115/200 to 230V ±10%	Single-phase	50/60Hz	600VA or less
SRCP-20A	AC100 to 115/200 to 230V ±10%	Single-phase	50/60Hz	1000VA or less

c CAUTION

If the power supply voltage drops below the above range during operation, the alarm circuit will work and return the SRCP 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 SRCP 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 SRCP controller.

2-2-2 Connecting the power supply

Connect the power supply to the power terminal block on the front panel of the SRCP 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.

The SRCP-05A, SRCP-10A and SRCP-20A have different connections to T1 and T2, depending on the input voltage.
