The pigtail fuses are integrated into wires ((1), black and blue)
inside the terminal box.
To replace the fuses it is necessary to replace both wires
completely (fixed with flat pin bushes (2)).
➨ Open the terminal box. Unscrew the four screws with a
Torx driver T20. Remove the terminal box cover. Remove
both wires with integrated fuses (fixed with flat pin bush-
es (2), see figure). Mount the new wires (flat pin bushes)
and close the terminal box. Fasten the cover with the four
screws.
The replacing of the fuse has to be carried out by a trained electrician.
Switch off the pump.
Disconnect the electrical power cord before opening the terminal box. After dis-
connecting from power, wait two minutes to allow the capacitors to discharge. After
replacing the fuse, the pump must be checked for electric safety (see below)! Identify
and eliminate the cause of failure before switching on the pump again.
Important: Check operability and safety of the pump after repair and after
replacing the device fuse.
Check the electrical safety (protective conductor resistance, insulating resis-
tance, high voltage test) according to IEC 61010 and national regulations.
