*1. The inrush current may vary depending on the operating condition and other conditions. Therefore, select fuses,
       breakers, and external power supply devices that have enough margin in characteristic and capacity,
       considering the condition under which the devices are used.
*2. If the ambient temperature is higher or the Controller is hot-started, the inrush current given in the table may be
       exceeded by up to twice the given value because the thermistor element with a low-temperature current control
       characteristic is not sufficiently cool.
*3. Of the inrush current values, the latter value varies depending on the input voltage and may rise to approx. 8.3 A
       at 20.4 VDC.
*4. 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.
*5. Apply the voltage between the Power Supply Unit’s L1 or L2 terminal and the GR terminal when testing insulation and
       dielectric strength. The tests can also be performed with the LG terminal and GR terminal connected to each other.
       In this case, the leakage current will be 10 mA or less.
*6. The primary DC power supply and the secondary DC power supply are not isolated.
*7. 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.
