Checking the unit leakage current
DANGER
Potentially lethal shock hazard!
It is essential to switch the unit off and to wait at least one more 1 minute
before beginning the check!
Prevent the device from unintentionally switching back on.
NOTICE
Important information on building installation
The connection and disconnection of the unit (power cable) to/from the
building installation must be performed by a qualified expert in
compliance with the national regulations. DIN VDE 0100-710 applies in
Germany.
Dentsply Sirona recommends an automatic tester (example illustration)
which complies with standard IEC 62353. If you do not use an automatic
tester, please pay attention to the specifications in the standard IEC
62353.
1. Switch the line voltage off at the main switch of the building
installation.
2. DANGER! Note the electrical safety rules without fail.
Disconnect the power cable and the second protective ground wire
from the building installation.
3. Attach a connector compatible with the tester (see the user's manual
for the tester) to the unit's power cable.
4. Plug the connector of your power supply unit into the intended socket
on the tester in accordance with the user's manual for the tester.
5. Check whether the unit power switch is turned on.
IMPORTANT
According to Note 2 in Table 3 of standard IEC 62353:2014, the
maximum device leakage current permitted by the manufacturer is 2 mA
for permanently connected units.
6. Perform the measurements according to the operating instructions of
the tester.
7. Document the measured value of the leakage current in the technical
"Inspection and maintenance and safety-related checks"
document
The measured value must not exceed 2.0 mA.
8. Reconnect the unit to the building installation (fixed connection) (see
the installation instructions for the unit).
