The S1, S2 and COM terminal should be short connect if you do not use S1-S4 terminals,
otherwise the VFD can not work.
6 INITIAL DEBUGGING
In order to ensure photovoltaic water supply system can work in efficiency, reliability and
steady, the parameters setting of controller and debugging for the first time were performed by
the professional electrical engineering technicist according to the following steps. (you’d
better choose a sunny day with strong sunlight to debugging.)
