7. Use a suitable multimeter to verify the absence of
voltage for L1, L2 and L3 to N at the AC terminal.
The maximum diameter of the test probe is 2 mm.
☑ If voltage is present, check the installation.
8. Verify the absence of voltage in L1, L2 and L3
against PE at the AC terminal.
☑ If voltage is present, check the installation.
9. Verify the absence of voltage in the multi-function
relay against PE at all terminals.
☑ If voltage is present, check the installation.
