minor or moderate injury or damage to property if the specified
actions are not taken.

NOTE

A potentially harmful situation can occur and, if not avoided, can
lead to property damage.

1.2 Staff qualifications

The device may only be transported, unpacked, installed, operated,
maintained and otherwise used by suitably qualified, trained and
authorized technical staff.
Only authorized 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

The safety hazards associated with the device must be assessed again
following installation in the final product.
Note the following when working on the device:

; Do not perform any modifications, additions or conversions on the

device without the approval of ebm-papst.

1.4 Voltage

; Check the device's electrical equipment at regular intervals; see

Chapter 5.2 Safety inspection.

; Replace loose connections and defective cables immediately.

DANGER
Electrically charged device

Risk of electric shock

→ When working on an electrically charged device, stand on a

rubber mat.

WARNING
Live terminals and connections even with device
switched off

Electric shock

W2E250-HJ32-01

Operating instructions

→ Wait five minutes after disconnecting the voltage at all poles

before opening the device.

CAUTION
In the event of a fault, the rotor and the impeller will be
energized

The rotor and the impeller have basic insulation.

→ Do not touch the rotor and impeller once installed.

CAUTION
The motor restarts automatically when operating voltage
is applied, e.g. after a power failure.

Risk of injury

→ Keep out of the device's danger zone.

→ When working on the device, switch off the line voltage

and ensure that it cannot be switched back on.

→ Wait until the device comes to a stop.

1.5 Safety and protective features

DANGER
Protective device missing and protective device not
functioning

Without a protective device there is a risk of serious injury, for
instance if the hands reach or are sucked into the device during
operation.

→ Operate the device only with a fixed protective device and

guard grille.# The fixed protective device must be able to
withstand the kinetic energy of a fan blade that becomes
detached at maximum speed. There must not be any gaps
which it is possible to reach into with the fingers, for example.

→ The device is a built-in component. As the operator, you

are responsible for ensuring that the device is secured
adequately.

→ Stop the device immediately if you notice a missing or

ineffective protective device.

1.6 Mechanical movement

DANGER
Rotating device

Risk of injury to body parts coming into contact with the rotor or
the impeller.

→ Secure the device against accidental contact.

→ Before working on the system/machine, wait until all

parts have come to a standstill.

WARNING
Rotating device

Long hair and dangling items of clothing, jewelry and the like
can become entangled and be pulled into the device. Injuries
can result.

→ Do not wear any loose-fitting or dangling clothing or jewelry

while working on rotating parts.#Protect long hair with a cap.

1.7 Emissions

WARNING
Depending on the installation and operating conditions,
the sound pressure level may exceed 70 dB(A).

Risk of noise-induced hearing loss

→ Take appropriate technical safety measures.

→ Protect operating personnel with appropriate safety

equipment such as hearing protection.

→ Also observe the requirements of local agencies.

1.8 Hot surface

CAUTION
High temperature on motor housing

Risk of burns

→ Ensure sufficient protection against accidental contact.

1.9 Transport

NOTE
Transporting the device

→ Transport the device in its original packaging only.

→ Secure the device so it cannot slip, e.g. by using a

lashing strip.

1.10 Storage

; Store the device, partially or fully assembled, in a dry and

weatherproof manner in the original packaging in a clean environment.

; Protect the device against environmental effects and dirt until final

installation.

; We recommend storing the device for no longer than one year in

order to guarantee trouble-free operation and the longest possible
service life.

; Even devices explicitly intended for outdoor use are to be stored as

described prior to commissioning.

; Maintain the storage temperature, see

Chapter 3.5 Transport and storage conditions.

2. INTENDED USE

The device is exclusively designed as a built-in device for conveying
air according to its technical data.
Any other usage above and beyond this does not conform with the
intended purpose and constitutes misuse of the device.
Customer equipment must be capable of withstanding the mechanical
and thermal stresses that can arise from this product. This applies for the
entire service life of the equipment in which this product is installed.

Intended use also includes

● conveying air at an ambient air pressure between 750 mbar and 1050

mbar.

● Using the device within the permitted ambient temperature range; see

Chapter 3.5 Transport and storage conditions and
Chapter 3.2 Nominal data.

● Operating the device with all protective devices.

● Following the operating instructions.

Improper use

In particular, operating the device in the following ways is prohibited and
could be hazardous:

● Operating the device in an unbalanced state, e.g. due to dirt deposits

or ice formation.

● Conveying air that contains abrasive particles.

● Conveying highly corrosive air, e.g. salt spray. Exception: devices

designed for salt spray and correspondingly protected.

● Conveying air with high dust content, e.g. suctioning off sawdust.

● Operating the device close to flammable materials or components.

● Operating the device in an explosive atmosphere.

● Using the device as a safety component or to perform safety-related
