Measurements
ATTENTION
Switch the power OFF at the main switch of the building installation
Select the correct current/voltage type and adjust the measuring range to match the expected readings.
Perform continuity tests only on units which are switched off.
ATTENTION
When opening the unit:
Please observe the usual precautionary measures for handling printed circuit boards (ESD).
Touch a ground point to discharge static electricity before handling any components.
ATTENTION
If the dental treatment center does not pass the safety tests, it must not be operated any longer!
You must advise the user of this fact in your capacity as service engineer. Corresponding repair work by
an authorized service engineer is required before putting the system into service again.
NOTE
The safety checks correspond to the standard IEC 62353:2007 (DIN EN 62353/VDE 0751-1:2008).
If you use an automatic tester, you can program it according to these standards.
– Application components Type B
– Permanently attached unit
– Protection Class I
The measurements to be performed are complex and time-consuming.
Sirona therefore explicitly recommends using an automatic tester.
