An emergency switch should be fitted in an easily
accessible place in the installation room (however,
outside any possible hazard zone).
This must be protected against damage and
unauthorised use!
We reserve the right to modify the dimensions and design as part of the ongoing technical development process.
CAUTION
The electrical unit connection must only be
carried out by authorised specialist person-
nel in accordance with the specifications of
the local power supplier.
