Warning
The enclosure class (IP65/Nema 4X) is only guaranteed if plugs or protective caps are
correctly installed!
Warning
The pump can start automatically when the mains voltage is switched on!
Do not manipulate mains plug or cable!
The mains plug is the separator separating the pump from the mains.
The rated voltage of the pump, see section 2.5 Nameplate, must conform to local conditions.
Warning
Electric circuits of external devices connected to the pump inputs must be separated from
dangerous voltage by means of double or reinforced insulation!
