17.10.3 DIELECTRIC STRENGTH TESTING OF THE RELAY
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 2 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.
