Note : Ensure that all units must be in operation. (Never use in condition that one of the units is not operated.)
Please select a bypass diode with maximum forward current rating more than output load current.
And maximum reveres voltage must withstand each power supply output voltage.
6-7. Isolation Test
Isolation resistance between Output - terminal is more than 100MΩ at 500VDC.
For safety operation, voltage setting of DC isolation tester must be done before the test.
Ensure that the unit is fully discharged after the test.
