your technical training and experience.
Safety instructions and
warnings
Warnings: Meaning
DANGER:
Indicates a possibly hazardous
situation which will result in death or serious
injuries if not avoided.
Danger of operating when
fan is not installed in its entirety.
Electric components are a potential
source of electric shock.
If the unit is open, all off the supply
circuits must be switched off (mains fuse
off), secured against being accidentally
switched back on and a visible warning
sign positioned.
Only operate the fan when it is
completely installed.
Do not cover the fan.
Risk of injury and health risk
in the event of changes or
modifications or if components which

is drilled at a point which is not permitted.
Danger of electric shock.
Before removing the housing cover
and before installing the electrics, switch
off all supply circuits as well as the mains
fuse and secure them against being
accidentally switched back on again.

corresponding parts.
A mains isolation device with contact
openings of at least 3 mm at each pole is
mandatory.
Only connect unit to permanently wired
electrical installation and with NYM-O or
NYM-J cables, depending on the unit
variant, 3x 1.5 mm² or 5x 1.5 mm².
The units may only be operated using
the voltage and frequency shown on the
rating plate.
Unit may also be energized even when
at a standstill and may be switched on
automatically by sensors (time delay,
humidity etc.) or by the thermo switch in
the motor winding. Maintenance and fault
