Installation and operating instructions Wilo-Yonos GIGA-N 63
CAUTION
Risk of material damage due to lack of ventilation of the electronic mod-
ule!
For motor power of ≥ 11 kW, the electronic module has a built-in speed-controlled
fan for cooling. The fan switches on automatically if the heat sink reaches 60 °C.
The fan draws in air from the outside, which is guided over the outer surface of the
heat sink. It only runs when the electronic module is operated under load. Depending
on the prevailing ambient conditions, dust is sucked in by the fan, which can accu-
mulate in the heat sink.
• Check the electronic modules from 11 kW for contamination at regular intervals.
• Clean fan and heat sink if required.
