Risk during transport from heavy or
falling loads.
Observe applicable
safety and accident prevention requirements.
Do not stand under a suspended load. Check
unit for transport damage.
Danger of electric shock when
operating a fan which is damaged or
not fully mounted.
Before working on the
fan, shut down all supply circuits (switch off
mains fuse), secure against being
accidentally switched back on and position a
visible warning sign.
Only operate the fan
when it is completely installed.
Do not
commission a damaged unit. Prevent the unit
from being switched back on until it has been
fully repaired.
Risk of injury in case of incorrect
mounting, if the fan falls down due
to its inherent weight.
The fan vibrates
slightly. Mounting only on roofs with sufficient
load-bearing capacity and with sufficiently
dimensioned mounting material.
Risk of burns due to hot motor. The
motor can still be hot after switching
off the device.
Cool-down time can be up to
30 minutes.
Danger if the relevant regulations
for electrical installations are not
observed.
● Before installing the electrics, shut down
all supply circuits, deactivate the mains
fuse and secure it so it cannot be switched
back on. Attach a warning sign in a clearly
visible place.
● Be sure to observe the relevant regula-
tions for electrical installation; e.g. EN
50110-1, in Germany this is particularly
VDE 0100, with the corresponding parts.
● A
service switch
must be fitted at the
installation location so that the unit can be
completely disconnected from the power
supply on site for cleaning, maintenance
or repair work. The service switch must be
secured against being switched on again.
● A mains isolation device with contact
openings of at least 3 mm at each pole is
mandatory. Only connect unit to a
permanently wired electrical installation
with type NYM-O/NYM-J (3 x 1.5 mm² or
5 x 1.5 mm²) cables.
● The units may only be operated using the
voltage and frequency shown on the rating
plate.
● Make electrical connections according to
wiring diagram.
● The degree of protection IP 55 (horizontal
installation position) stated on the rating
plate is only guaranteed if installation is
undertaken correctly and if the connecting
cable is correctly guided into the terminal
box. The terminal box cover must be
correctly fitted, so that the surrounding
sealing has close contact all the way
around the terminal box.
● With protection class I, connect the PE
conductor and check the connection.
● Check protective-conductor opening on
housing.
● 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 thermal protection
in the motor winding. Maintenance and
fault finding only permissible when carried
out by trained specialists.
Exercise caution when handling
packaging materials.
Observe
applicable safety and accident prevention
requirements. Store packaging material out of
the reach of children (risk of suffocation).
