13. If the neutral conductor is connected, use an
appropriate multimeter to ensure that no voltage is
present at the AC connecting terminal block
between
L1 and N , L2 and N , and L3 and N .
Insert the test probe of the multimeter into the round
opening in the terminal.
14. Use an appropriate measuring device to ensure that no voltage is present at the AC
connecting terminal plate between L1 and PE , L2 and PE , and L3 and PE . Insert the test
probe into each round opening of the terminal.
15. Ensure that no voltage is present between any terminal of the multifunction relay and PE of the
AC connecting terminal plate.
