Translation of the original operating instructions
For cyclic speed loads, note that the rotating parts of the device
are designed for maximum one million load cycles. If you have
specific questions, contact ebm-papst for support.
;
Use the device in accordance with its protection type.
Notes on surface quality
The surfaces of the products conform to the generally applicable industrial
standard. The surface quality may vary during the production period.
Strength, dimensional stability and dimensional accuracy are not affected
by this.
The colour pigments of the paints used react perceptibly to UV light over
the course of time. This does not however have any influence on the
technical properties of the products. To prevent the formation of patches
and fading, the product is to be protected against UV radiation. Changes
in colour are not a reason for complaint and are not covered by the
warranty.

4. CONNECTION AND START-UP
4.1 Connecting the mechanical system
CAUTION
Cutting and crushing hazard when removing the fan
from the packaging
→ Carefully hold the impeller to remove the device from its
packaging. Make sure to avoid any shock.
→ Wear safety shoes and cut-resistant safety gloves.
CAUTION
Heavy load when taking out the device
Bodily harm, e.g. back injuries, are possible.
→ Two people should remove the device out of its packaging
together.
NOTE
Damage to device from vibration
Bearing damage, reduced service life
→ Forces or impermissibly high vibration levels must not be
transmitted to the fan from system components.
→ If the fan is connected to air ducts, it should isolated from
vibrations, for example using compensators or similar
elements.
→ Fasten the fan to the substructure without distorting it.
;
Check the device for transport damage. Damaged devices must no
longer be installed.
;
Install the undamaged device according to your application.
CAUTION
Possibility of damage to the device
Serious damage may result if the device slips during assembly.
→ Keep the device fixed in position at the installation location
until all attachment screws have been tightened.
●
The fan must not be strained on fastening.
4.2 Connecting the electrical system
DANGER
Electric voltage on the device
Electric shock
→ Always install a protective earth first.
→ Check the protective earth.
DANGER
Incorrect insulation
Risk of fatal injury from electric shock
→ Use only cables that meet the specified installation
requirements for voltage, current, insulation material, load etc.
→ Route cables such that they cannot be touched by any
rotating parts.
DANGER
Electrical load (>50 µC) between mains wire and
protective earth connection after switching of the supply
when switching multiple devices in parallel.
Electric shock, risk of injury
→ Make sure that sufficient protection against accidental contact
is provided.
Before working on the electrical connection, the
connections to the mains supply and PE must be shorted.
