A lockable main switch must be connected upstream to the control unit, which switches off the
mains voltage to the control unit at all poles. In addition, a fuse must be provided on site in the
supply circuit to protect the supply line and terminals.
4.4 CARRYING OUT OF THE TEACH-IN RUN
After connecting the external devices, the teach-in run is carried out while the housing cover is
still open.
4.5 TERMINATION OF WIRING
After completion of the teach-in run, the protective conductor connection to the housing cover
must be re-established.
Before closing the cover, check again whether all protective conductor connections have been
made reliably!
Now screw on the housing cover again. Make sure that the screws are tightened only slightly
in order not to damage the seal.
The assembly of the device is now completed.
WARNING! ELECTRIC HAZARD!
The mains supply has to be disconnected
before the start of electrical work.
