*1. The AC and DC values above are given for a cold start, and the AC values are at room temperature. The AC inrush
control circuit uses a thermistor element with a low-temperature current control characteristic. If the ambient
temperature is high or the Controller is hot-started, the thermistor will not be sufficiently cool, and the inrush
current given in the table may be exceeded by up to twice the given value. The DC inrush control circuit uses a
capacitor-charging delay circuit. If the power is OFF for only a short time for a hot-start, the capacitor will not
sufficiently discharge and the inrush current given in the table may be exceeded by up to twice the given value. An
inrush current of approximately 4 A may occur and continue for 1 s when the power is turned ON. When selecting
fuses, breakers, and external DC power supply devices for external circuits, allow sufficient margin in shut-off
performance.
*2. 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.
*3. Supported only when mounted to CPU Rack.
*4. The tests can also be performed with the LG terminal and GR terminal connected to each other.
*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.
