1 - Ekip Touch maintenance and troubleshooting

Introduction Correct maintenance of the unit and connected devices ensures they operate correctly over time.
The maintenance operations must be performed by expert personnel, as required by the safety regulations
and maintenance schedule described in this document and in the manuals 1SDH000999R0002 and
1SDH001000R0002).
If faults are discovered, find out what is causing them and eliminate them before putting the unit back
into service.
WARNING! Detecting faults must only be managed by (electrically) skilled persons (IEV
195-04-01: person with relevant education and experience to enable him or her to perceive
risks and to avoid hazards which electricity can create), as it may be necessary to perform
insulation and dielectric tests on part or all the installation
