4-7. Series Operation
For series operation, either method (A) or (B) is possible.

(*1)Please select a bypass diode with maximum forward current rating more than output load current. And maximum reverse voltage must
withstand each power supply output voltage.
4-8. Parallel Operation
No current balance function, not recommend.
4-9. Isolation Test
Isolation resistance between Output – FG is more than 100M Ω a t 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.
4-10. Withstand Voltage
This series is designed to withstand 4.0kVAC between input and output, 1.5kVAC between input and
each for 1 minute. When testing withstands voltage, set current limit of the withstand voltage test equipment to 20mA. The applied 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.
4-11. Auxiliary Supply
Auxiliary supplies - FAN Supply （ a vailable only with option models ） : 12V/0.3A , Standby Mode Power: 5V/0.5A, are provided to ease
customer application. FAN Supply 12V can be used to drive customer system fan. Standby Mode Power 5V can be used as customer system
