4 - Possible connections
It is possible to start or stop the pump with the
external control(*) (potential-free contact);
this function takes precedence over the other
functions.
This external control can be removed by bridging
the terminals (11 and 12).
Examples: Float switches,
low water pressure switches, etc.
The frequency converter is equipped with an
error relay with normally open contact (**):
Contact open = frequency converter is receiving
no voltage or is defective
