Keep the distance between the insulating transformer
(or the noise filter) and the power supply module as
short as possible, and the cable must be twisted
densely.
Do not bundle up and di not close
100V AC:85 to132V AC

1) Wiring of power supply
For AC power supply
Wire to a 100 to 120V AC or 200 to 240V AC power supply.
The thickness of the wire must be 2mm
2
, and the wire must ne twisted densely.
For DC power supply
Wire to a 24V DC power supply (22.8-26.4V DC).
The thickness of the wire must be 2mm
2 , and the wire must ne twisted densely.
[Tips]
The tolerance range of MICREX-SX AC power supply is 85 to 132V AC for 100V AC, and 170 to 264V AC for 200V AC. But
the voltage is recommended to be as near the rated voltage (100 to 110V AC, 200 to 220V AC) as possible.
In the case of the lower voltage, a small voltage drop will cause a power failure. In the case of the higher voltage, the heat-
ing value of the power supply module increases and it reduces the life of the module. If power supply voltage fluctuation
exceeds the specified range, connect a voltage stabilizer to the power supply.
For noise reduction of the power supply, an insulating transformer or a noise filter is effective between the breaker and the
power supply module. Take care of the following points:
• Do not bundle up or do not close the insulating transformer or the noise filter.
• Keep the distance between the insulating transformer (or the noise filter) and the power supply module as short as
possible, and the cable must be twisted densely.
