F&F CP-721-FPV - 3-Phase Installation Wiring; 3-Phase Wiring Diagram

- 6 -
When installing the relay for 3-phase photovoltaic instal-

relay to the phase with the highest voltage overshoot,
or to use a separate relay for each phase and control the
load via an additional phase switch. An example wiring
diagram is shown in the figure below:
