English
Have work on the electrical part of the pump carried out only by a qualified electrician.
The power supply and control cable is connected at the factory and electrically tested!
Cable removal requires an earth contact and insulation resistance test according
to VDE 0701-0702.
• The electrical connection must be established via a fixed power cable (3 x 1.5 mm
mum cross-section), equipped with a plug and socket connector or an all-pole switch
with a minimum contact opening width of 3 mm.
• The mains connection cable is to be routed into the system's switchbox with a strain relief.
The strain relief and tightness against dripping water/condensation water must be ensured.
The cable is to be provided with a drip loop if necessary.
• The following minimum requirements are to be met if shutdown takes place by means
of an on-site network relay: Rated current ≥ 8 A, rated voltage 250 V AC, contact
materials: AgSnO2 or Ag/Ni 90/10.
• Fuse protection: 10/16 A, slow-blow or automatic fuse with C characteristic.
• A motor protection switch supplied by the customer is not required. Nevertheless, if such
a protection switch is available in the installation, it must be bypassed or set to the highest
possible current.
• It is recommended to safeguard the pump with a residual-current device.
Labelling: residual current type A
When dimensioning the residual-current device, consider the number of pumps con-
nected and their rated motor currents.
• Leakage current per pump I
