6. OPERATING INSTRUCTIONS

6.1. RPE – CONTINUITY MEASUREMENT ON MODULES/STRINGS/PV FIELDS
The purpose of this measurement is performing a continuity test of the protective and
equipotential conductors (e.g.: from rod to earth and connected foreign earth) and earth
rods of SPDs on PV installations. The test must be carried out using a test current >
200mA according to the prescriptions of IEC/EN62446-1 and IEC/EN61557-4 guidelines.
