CJ1W-PA/PD
*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.

dimensions
90.7 to 466.7 × 90 × 65 mm (W × H × D) (not including cables)
Note: W = a + b + 20 × n + 31 × m + 14.7
a: Power Supply Unit: PA205R and PA205C = 80; PA202 = 45; PD025 = 60; PD022=27
b: CPU Unit: CJ1-H or CJ1 = 62; CJ1M-CPU1@ = 31; CJ1M-CPU2@ = 49
The total width is given by the following: W = 156.7 + n × 20 + m × 31, where n is the number of 32-point I/O Units or I/O Control Units
and m is the number of other Units.
Safety measures Conforms to cULus and EC Directives.
