FLENDER COUPLINGS N-EUPEX 3103en, Assembly And Operating Instructions Manual, Page: 13 / 64

Secure the drive unit against being switched on accidentally. Attach a notice to the switch
stating clearly that work is being carried out on the coupling. Ensure that the entire unit is not
under load.
2.2 Intended use
Only use the coupling according to the conditions specified in the service and delivery contract
and the technical data in the annex. Deviating operating conditions are considered improper
use. The user or owner of the machine or plant is solely liable for any resulting damage.
When using the coupling please specifically observe the following:
• Do not make any modifications to the coupling that go beyond the permissible machining
described in these instructions. This also applies to touch protection facilities.
• Only use original spare parts from Flender. Flender only accepts liability for original spare
parts from Flender.
Other spare parts are not tested and approved by Flender. Non-approved spare parts may
possibly change the design characteristics of the coupling and thus impact active and/or
passive safety.
Flender will accept no liability or warranty whatsoever for damage occurring as a result of the
use of non-approved spare parts. The same applies to any accessories that were not supplied
by Flender.
If you have any queries, please contact our customer service (see Service and support
(Page 45)).
