7-5.  Isolation Test

Isolation resistance between Signal -      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 product is fully discharged after the test.

 ■

 Signal -         terminal : 500VDC More than 100MΩ

7-6.  Withstand Voltage

The product is designed to withstand 3.0kVAC between input/buffer output and signal, 2.0kVAC between input/buffer
output and      terminal and 500VAC between signal and      terminal each for 1 minute.
When testing withstand voltage, set current limit of withstand voltage test equipment at 10mA (Signal -       terminal : 
20mA).
The applied voltage must be gradually increased from zero to testing value and then gradually decreased for shut down. 
When timer is used, the product may be damaged by high impulse voltage at switch on and off timing. Connect input/buffer 
output and signal output as follows.

 ■

 Input/Buffer output - Signal (dotted line) : 3.0kVAC, 1min (10mA)

   

Input/Buffer output -            (solid line) : 2.0kVAC, 1min (10mA)

 ■

 Signal -           : 500VAC, 1min (20mA)
