8.7.3 DIELECTRIC STRENGTH TESTING
A fully assembled production version of the relay is tested in its metal case. The dielectric strength of all the input/output
terminals are tested with respect to its grounded chassis and Terminal G12 (safety ground). The test voltage of the tester,
from the initial value of 0 V AC, is raised to 1.6 kV AC in such a manner (slowly) that no appreciable transients occur. The
voltage is maintained for 1 minute and is then reduced smoothly to zero as rapidly as possible. According to IEC255-5, the
Hi-Pot test is repeated with a voltage not less than 500 V AC.
