Normally, no maintenance work must be carried out inside the housing. Repairs may only be carried
out by the manufacturer or authorized workshops. Exceptions are the replacement of fuses and the
change of the factory parameters with the help of the DIP switches. For all work that requires
opening the housing, be sure to pay attention to the following points:
•
Turn off the control on the main switch and unplug the power plug.
•
Wait about 2 minutes so that the energy stored in the capacitors can
discharge.
•
Failure to comply with this instruction is a danger to life due to an
electric shock.
The control can also be damaged if objects accidentally
fall into the controller when opening the case.
•
If the controller is opened directly after operation, individual components
in the controller can still have temperatures of more than 50°C. When
touching, there is a risk of burn. We therefore recommend that you
comply with a cooling time of 30min
•
Store all screws and dismantled small parts carefully. During the
subsequent assembly, make sure to mount all original parts again in the
designated place. Too long screws can cause short circuits, or damage
components inside.
•
Metallic housing parts must be connected to the protective conductor.
When assembling, make sure to reconnect all grounding lines and tighten
screws firmly.
