off in case of overload. The fan must remain
switched off long enough for the motor to cool
down, before starting the fan back up.
Depending on size and temperature
conditions, it may take up to 30 mi-
nutes to cool down. Only then can
the unit be switched back on.
EC units: The internal control electronics
prevent the fan from overheating/overload
(thermal fuse/thermal circuit breaker in motor
winding).

6. Operation: Switching on/off

The fan is switched on and off with a switch,
for example, with a suitable 3-step switch.
