(do not perform discharging at low impedance. it may cause deterioration.) in any case, take full countermeasures for electric-shock preven- tion. power supply terminal connection at insulation and withstand voltage tests short output or input terminals. connections between testers and power supply at insulation and withstand voltage tests for connections between the testers and the power supply body, couple the tester terminals at the corresponding locations listed below before executing the tests. precautions when using this unit, make sure that the ambient temperature of the power supply is within the operating temperature range. the "ambient temperature of the power supply" refers to the temper- ature near the power supply inside the device in which the unit is installed. install space at least 10 mm away from other components on sides. make sure to choose input/output wiring and noise filters that can safely accommodate their respective current capacities. if the power supply is not used for extended periods of time, we recommend that you apply input voltage for about one hour every two years to maintain the capacitor?s performance. when power supplies are used serially, the rated current will be limited by the power supply with the lowest rated current. also make sure to connect a reverse voltage protection diode (with- stand voltage: twice that of the combined output voltage. for- ward current: twice that of the output current. forward voltage drop: as small as possible) to prevent damage to the interior components caused by reverse voltage. the materials used in these products are free of designated bro- mine flameproof materials (pbdpes and pbbs). specific ods has not been used in the production of these prod- ucts. test conditions withstand voltage tester insulation tester + terminal ?terminal + terminal ?terminal input-to-output withstand voltage 13?? input-to-fg withstand voltage 12?? output-to-fg withstand voltage 32?? input-to-fg insulation ??1 2 input-to-output insulation ??1 3 output-to-fg insulation ??3 2 +s -s ref rv cb +pf -pf +rc -rc l3 l2 l1 .adj v on 1 in put terminal 2 fg 3 output terminal
