● Operation in medical equipment with a life-sustaining or life-support
function.
● Conveying solids in the flow medium.
● Painting the device
● Connections (e.g. screws) coming loose during operation.
● 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.

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, aluminum and plastic.
Metallic materials are generally considered to be fully recyclable.
Separate the components for recycling into the following categories:
● Steel and iron
● Aluminum
● 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
● Power cables
● Cables for internal wiring
● Electrolytic capacitors
Dispose of electronic components employing the proper procedures for
electronic scrap.

→ Please contact ebm-papst for any other questions on disposal.
