The number of starts/stops via the mains voltage must
not exceed one-time per minute.
If a higher number of starts/stops is required then the
start/stop digital input must be used (mains voltage
directly connected). This is the preferred method of
starting and stopping Design Envelope Pumps.
The three phase mains must be isolated before
performing maintenance of the pump.
