Specifications Section 2-1
Note 1. Disconnect the Power Supply Unit’s 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.
