Translation of the original operating instructions
Unacceptable
operating point (e.g.
counterpressure is
too high)
Correct the operating
point. Let the device
cool down.
To reset the error
message, switch off
the mains supply
voltage for a min. of
25 s and switch it on
again.
Alternatively, reset
the error message by
applying a control
signal of <0.5 V to
DIN1 or by short
circuiting Din1 to
GND.
Deflagration
Leakage of the
handled air/gas mixture
Check for leaks;
replace blower if not
properly sealed
If you have any other problems, contact ebm-papst.
6.1 Cleaning
NOTE
The device does not need to be cleaned.
6.2 Safety test
NOTE
High-voltage test
The integrated EMC filter contains Y capacitors. Therefore, the
trigger current is exceeded when AC testing voltage is applied.
→ Test the device with DC voltage when you carry out the
high-voltage test required by law. The voltage to be used
corresponds to the peak value of the AC voltage required by
the standard.

6.3 Disposal
For ebm-papst, environmental protection and resource preservation are
top priority corporate goals.
ebm-papst operates an environmental management system which is
certified in accordance with ISO 14001 and rigorously implemented
around the world on the basis of German standards.
Right from the development stage, ecological design, technical safety
and health protection are fixed criteria.
The following section contains recommendations for ecological disposal
of the product and its components.
6.3.1 Country-specific legal requirements
NOTE
Country-specific legal requirements
Always observe the applicable country-specific legal
regulations with regard to the disposal of products or waste
occurring in the various phases of the life cycle. The
corresponding disposal standards are also to be heeded.
6.3.2 Disassembly
Disassembly of the product must be performed or supervised by
qualified personnel with the appropriate technical knowledge.
The product is to be disassembled into suitable components for disposal
employing standard procedures for motors.
WARNING
Heavy parts of the product may drop off. Some of the
product components are heavy. These components
could drop off during disassembly.
This can result in fatal or serious injury and material damage.
→ Secure components before unfastening to stop them falling.
6.3.3 Component disposal
The products are mostly made of steel, copper, aluminium and plastic.
Metallic materials are generally considered to be fully recyclable.
Separate the components for recycling into the following categories:
●
Steel and iron
●
Aluminium
●
Non-ferrous metal, e.g. motor windings
●
Plastics, particularly with brominated flame retardants, in accordance
with marking
●
Insulating materials
●
Cables and wires
●
Electronic scrap, e.g. circuit boards
Only ferrite magnets and not rare earth magnets are used in external
rotor motors from ebm-papst Mulfingen GmbH & Co. KG.
;
Ferrite magnets can be disposed of in the same way as normal iron
and steel.
Electrical insulating materials on the product, in cables and wires are
made of similar materials and are therefore to be treated in the same
manner.
The materials concerned are as follows:
●
Miscellaneous insulators used in the terminal box
