The dry running protection function is active in automatic mode and manual mode.
A digital input is provided for connecting dry running protection equipment. When
the input is open, the control unit detects dry running and stops the pressure booster
system after approx. 10 seconds (factory setting).

Terminal wiring diagram
5.9.1 Power terminals
NOTE
The PumpDrive is wired to the master switch, the motor and the pressure sensor at the
factory. Work at the power terminals is only required if the PumpDrive needs to be
removed.
The power terminals are located underneath the V-shaped cover.
DANGER
Electrical connection work by unqualified personnel
Danger of death from electric shock!
▷
Always have the electrical connections installed by a trained electrician.
▷
Observe regulations IEC 30364 (DIN VDE 0100) and, for explosion-proof models,
