4-8. Isolation Test
Isolation resistance between output and
shall be more than 100M 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.

This series is designed to withstand 4243VDC between input
and output, 2500VDC between input and
Earth) and 707VDC between output and the
Earth) for 1 minute each. When testing withstand voltage, set
current limit of the withstand voltage test equipment to 20mA
(Output -
voltage must be gradually increased from zero to the testing
value and then gradually decreased for shut down. When timer
is used, the power supply may be damaged by high impulse
voltage at timer switch on and off. Connect input and output
as follows.
