Electrical connection
The SILENT is an extractor fan designed
for a single-phase supply, with voltage
and frequency as indicated on the rating
plate of the unit.
The units are manufactured with double
electrical insulation (Class II) and
therefore they do not need an earth
connection.
The electrical cable must enter the
SILENT through the cable entry (4).
The SILENT must be connected to the
electrical supply in accordance with local
wiring regulations.
Once the cable has been introduced
proceed using the electrical wiring
diagram applicable to the selected
model.
