2. Product information │ uk
●
ERR .. and ERR .. S: Model with external
rotor capacitor motor. Operating capacitor
pre-wired in terminal box.
●
ERR .. N: Low-energy model with reduced
speed. Operating capacitor pre-wired in
terminal box. ERR 16/1 N and ERR 20/1 N
with extra 2nd capacitor in inside, pre-
wired.
Thermal overload protection
The fan motor has thermal protection
(temperature sensor in the motor winding).
The overload protection automatically
switches the fan off in the event of
overheating.
The fan must remain switched off long
enough for the motor and temperature limiter
to cool down, before starting the fan back up.
Depending on size and temperature condi-
tions, it may take up to 10 minutes to cool
down. Only switch unit on after this.

2.3 Intended use

●
ERR are duct fans for domestic and light-
duty commercial use.
●
These fans are used for air extraction or
venting, for example in the machine area,
workplace, production site, storage room,
lab, workshop, break area or rooms
without windows.
●
IP X4 type protection is only satisfied
when installed in ventilation ducts, on
the inlet and outlet sides with at least 1 m
of duct.
●
Operation is only permitted:
● with the ERR fan installed directly in the
duct. Folded spiral-seam ducts of the
appropriate nominal size are permitted for
the duct.
● with an ERR fan permanently installed
on the wall, ceiling or bracket. We
recommend the optional FUR attachment
foot for mounting. The mounting location
must demonstrate sufficient load-bearing
capacity.
