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.

1.7 Mechanical movement

DANGER
Danger of injury from open blower

Gas escapes. When the blower is open, you come into contact
with rotating and electrically live parts. Escaping gas may also

Translation of the original operating instructions

cause explosions.

→ Never open the blower.

DANGER
Flying parts

Missing safety devices may cause balancing weights or
broken fan blades to be ejected at high speeds, causing bodily
harm.

→ Take appropriate safety measures.

WARNING
Rotating device

Long hair, loose items of clothing and jewellery could become
entangled and pulled into the device. You could be injured.

→ Do not wear any loose clothing or jewellery while working

on rotating parts.

→ Protect long hair by wearing a cap.

WARNING
Flying parts

Missing safety devices may cause fan blades to be ejected at
high speeds, causing bodily harm.

→ Take appropriate safety measures.

The safety devices must prevent contact with rotating parts
and the printed circuit board.

1.8 Deflagration

DANGER
Gas escapes through leaky housing after deflagration

Danger of injury

→ After a deflagration, check that the housing of the gas blower

is tightly sealed.

→ Replace any gas blower with a leaky housing.

DANGER
Fire and deflagration hazard

The gas blower is not approved according to Ex protection
guidelines. Rotating parts can scrape against stationary parts.
This may cause sparks and chips. The surface temperature
may rise, resulting in a fire.

→ Check which hazards arise from installing, operating,

servicing or disposing the gas blower in conjunction with
your device.
Prevent these hazards.
Carry out all appropriate measures to this purpose.

1.9 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.

1.10 Hot surface

CAUTION
High temperature at the electronics enclosure

Danger of burn injuries

→ Ensure that sufficient protection against accidental contact is

provided.

1.11 Transport

NOTE
Transport of blower

→ Transport the blower in its original packaging only.

→ Secure the blower so that it does not slip, e.g. by using a

clamping strap.

1.12 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.
