Safety checks
Medical equipment is designed in such a way that the
first occurrence of a fault does not create a hazard to the
safety of patients, users or other persons. Hence it is
important to detect such faults before a second fault
occurs, which might then lead to safety hazards.
For that reason it is essential to perform safety tests
every 2 years
which aim particularly at detecting electri-
cal faults (e.g. isolation defects). This is done by an
authorized service engineer from your dental depot,
most practically together with the work to be performed
according to section 17.2.
The check includes a visual inspection as well as mea-
surements of the protective ground wire connections
and the equivalent leakage currents.
The inspections and measurements to be performed are
specified in the
“Maintenance Manual”
. The measured
values must be documented there by the service engi-
neer.
Safety tests must also be performed and documented
during
initial startup
, after extensions/upgrades (
con-
version
) of your treatment center and after
repair work
which might affect the electrical safety of the system.
NOTICE
i
The treatment center must not be operated if it has failed
to pass the safety tests!

Maintenance Manual
Keep this document near your treatment center.
Any inspection and maintenance work as well as all
safety tests are documented by the service engineer in
the Maintenance Manual.
We recommend that the user always keep the documen-
tation in the chapter
“Reporting of incidents to author-
ities / manufacturers”
up-to-date, regardless of any
legal requirements.
