An emergency switch must be installed in an eas-
ily accessible place in the installation room (but
outside any possible hazard zone).
This must be protected against damage and unau-
thorised 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 personnel
in accordance with the specifications of the
local power supplier.
