1.1 Levels of hazard warnings
These operating instructions use the following hazard levels to indicate
potentially hazardous situations and important safety regulations:
DANGER
Indicates an imminently hazardous situation which, if not
avoided, will result in death or serious injury. Compliance with
the measures is mandatory.
WARNING
Indicates a potentially hazardous situation which, if not avoided,
could result in death or serious injury. Exercise extreme
caution while working.
CAUTION
Indicates a potentially hazardous situation which, if not avoided,
may result in minor or moderate injury or damage of property.
NOTE
A potentially harmful situation can occur and, if not avoided, can
lead to property damage.
1.2 Staff qualification
The device may only be transported, unpacked, installed, operated,
maintained and otherwise used by qualified, trained and authorised
technical staff.
Only authorised specialists are permitted to install the device, to carry
out a test run and to perform work on the electrical installation.
1.3 Basic safety rules
Any safety hazards stemming from the device must be re-evaluated
once it is installed in the end device.
Observe the following when working on the unit:
; Do not make any modifications, additions or conversions to the
device without the approval of ebm-papst.
1.4 Electrical voltage
; Check the electrical equipment of the device at regular intervals, refer
to chapter 6.2 Safety test.
; Replace loose connections and defective cables immediately.
DANGER
Electrical load on the device
Risk of electric shock
→ Stand on a rubber mat if you are working on an electrically
charged device.
WARNING
Terminals and connections have voltage even with a
unit that is shut off
Electric shock
→ Wait five minutes after disconnecting the voltage at all poles
before opening the device.

Operating instructions
CAUTION
In the event of failure, there is electric voltage at the
rotor and impeller
The rotor and impeller are base insulated.
→ Do not touch the rotor and impeller once they are installed.
CAUTION
If control voltage is applied or a speed setpoint is stored,
the motor automatically restarts, e.g. after a power failure.
Danger of injury
→ Keep out of the danger zone of the device.
→ When working on the device, switch off the mains
supply voltage and secure the latter from being switched on
again.
→ Wait until the device stops.
→ After working on the device, remove any used tools or
other objects from the device.
1.5 Safety and protective functions
DANGER
Missing safety device and non-functioning safety device
If there is no safety device, you could be seriously injured, for
example if you reach into the running device or your hands are
sucked into it.
→ Operate the device only with a fixed and isolating safety
protection and a fixed guard grille.
The guard must withstand the kinetic energy of a fan blade
detaching at maximum speed.
→ The device is a built-in component. You, the owner/
operator, are responsible for providing adequate protection for
the device.
→ Shut down the device immediately if you detect a
missing or ineffective protective feature.
1.6 Electromagnetic radiation
Interference from electromagnetic radiation is possible, e.g. in conjunction
with open and closed-loop control devices.
If unacceptable emission intensities occur when the fan is installed,
appropriate shielding measures have to be taken by the user.
NOTE
Electrical or electromagnetic interferences after
integrating the device in installations on the customer's
side.
→ Verify that the entire setup is EMC compliant.
→ Do not wear any loose clothing or jewellery while working
on rotating parts.
→ Protect long hair by wearing a cap.
1.8 Emission
WARNING
Depending on the installation and operating conditions,
a sound pressure level greater than 70 dB(A) may arise.
Danger of noise-induced hearing loss
→ Take appropriate technical safety measures.
→ Protect operating personnel with appropriate safety
equipment, e.g. hearing protection.
→ Also observe the requirements of local agencies.
1.9 Hot surface
CAUTION
High temperature at the electronics enclosure
Danger of burn injuries
→ Ensure that sufficient protection against accidental contact is
provided.
1.10 Storage
; Store the device, partially or fully assembled, in a dry and
weatherproof manner in the original packing in a clean environment.
; Protect the device from environmental impacts and dirt until the final
installation.
; We recommend storing the device for a maximum up to one year to
guarantee proper operation and longest possible service life.
; Even devices explicitly suited for outdoor use are to be stored as
described prior to being commissioned.
; Maintain the storage temperature, see
chapter 3.6 Transport and storage conditions.
; Please make sure that all screwed cable glands are fitted with
dummy plugs.
1.11 Disposal
When disposing of the device, please comply with all relevant
requirements and regulations applicable in your country.
1.7 Mechanical movement
DANGER
Rotating device
Body parts that come into contact with the rotor and impeller
can be injured.

2. PROPER USE
The device is exclusively designed as a built-in device for moving air
according to its technical data.
Any other or secondary use is deemed improper and constitutes a
misuse of the device.
Installations on the customer's side must meet the mechanical, thermal
and service life-related stresses that can occur.
Proper use also includes:
● Use the device in power systems with earthed neutral (TN/TT power
systems) only.
● Moving air with a density of 1.2 kg/m³.
● Using the device in accordance with the permitted ambient
temperature, see chapter 3.6 Transport and storage conditions and
chapter 3.2 Nominal data.
● Operating the device with all protective features in place.
● Minding the operating instructions.
Improper use
Using the device in the following ways is particularly prohibited and
may cause hazards:
● Operating the device with an imbalance, e.g. caused by dirt deposits
or icing.
● Opening the terminal box during operation.
● Moving air that contains abrasive particles.
● Moving highly corrosive air, e.g. salt spray mist. Exceptions are
devices that are intended for salt spray mist and protected accordingly.
● Moving air that contains dust pollution, e.g. suctioning off saw dust.
● Operating the device close to flammable materials or components.
● Operating the device in an explosive atmosphere.
● Using the device as a safety component or for taking on safety-
