3.10 Earth of aligner
The SSENCE aligner urgently need a correct earth to work perfect. All the new models coming
after January 2015 do have a better and correct connected earth included in the cabinet.
If there are problems with the older machines (black cameras, freezing of screen or extensive
slow working operations), one reason for this can be a bad earth connection. The machine
urgently needs an update of the earth connection.

not
sure if there is a good earth over the 220v power chord:
- use the delivered earth pin and connect on the earth screw on outside the housing, or
- connect earth to a heater or water tube.
If it is sure that the 220V power chord is earthed:
- the connection between earth connector and power
chord must be done inside the machine:
