6. If required, remove additional cables (sensors, signals etc.).

CAUTION
Risk of material damage if the electronic module is not in-
stalled!
Normal operation of the pump is only permitted with the electronic
module installed!
The pump must not be connected or operated without the electronic
module being installed!
NOTICE
The electronic module must be dismantled and installed ac-
cording to the instructions enclosed with the spare part!
CAUTION
Risk of material damage due to lack of ventilation of the elec-
tronic module!
For motor powers ≥ 11 kW, the electronic module features a built-in
speed-controlled fan for cooling. The fan switches on automatically
when the heat sink reaches 60 °C.
The fan draws in air from the outside, which is guided over the outer sur-
face of the heat sink. It only runs when the electronic module is operated
under load. Depending on the prevailing ambient conditions, dust drawn
in via the fan might collect in the heat sink.
• Check electronic modules ≥ 11 kW for contamination at regular inter-
vals.
• Clean fan and heat sink if required.
Installation must be carried out based on the detailed drawings in the section "Dismantling"
as well as the general drawings in the section "Spare parts".
• Clean and check the single components for wear before installation. Damaged or worn
parts must be replaced with original spare parts.
• Coat location points with graphite or something similar before installation.
• Check the O-rings for damage and replace if necessary.
• Flat gaskets must be constantly replaced.
