Safety measures	Conforms to cULus and EC Directives.

*1. Disconnect the Power Supply Units LG terminal from the GR terminal when testing insulation and dielectric strength.
Testing the insulation and dielectric strength with the LG terminal and the GR terminals connected will damage
internal circuits in the CPU Unit.
*2. Supported only when mounted to CPU Rack.
*3. The inrush current is given for a cold start at room temperature. The inrush control circuit uses a thermistor element
with a low-temperature current control characteristic. If the ambient temperature is high or the PLC is hot-started, the
thermistor will not be sufficiently cool, and the inrush currents given in the table may be exceeded by up to twice the
given values. When selecting fuses or breakers for external circuits, allow sufficient margin in shut-off performance.
*4. Maintain an ambient storage temperature of −25 to 30°C and relative humidity of 25% to 70% when storing the Unit for
longer than 3 months to keep the replacement notification function in optimum working condition.
*5. Change the applied voltage gradually using the adjuster on the Tester. If the full dielectric strength voltage is applied
or turned OFF using the switch on the Tester, the generated impulse voltage may damage the Power Supply Unit.
*6. CJ1W-PD022 is not insulated between the primary DC power and secondary DC power.
*7. Internal components in the Power Supply Unit will deteriorate or be damaged if the Power Supply Unit is used for an
extended period of time exceeding the power supply output capacity or if the outputs are shorted.
*8. Final order entry date for CJ1M :The end of March, 2021
