       2 - 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 (see recipients, Safety requirements and Maintenance schedule).
                                    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

                                           insulation and dielectric tests on part or all the installation



             Inspections and general  Perform the following inspections:
                           cleaning  •  check to make sure that Ekip Touch is clean. Remove any dust and traces of other materials with
                                       a clean, dry cloth (use a mild detergent if necessary; a laminate thinner such as Henkel 273471 or
                                       Chemma 18 or equivalent can be used if there is a heavy coating of dirt)
                                     •  check that there are no foreign objects near the connectors or terminals


            Inspection of Ekip Touch Perform the inspections described in chapter 1 - Putting into service, including an inspection of the state
                                    or the wiring, modules and accessories:
                                     •  verification of alarms
                                     •  check that the modules (internal and external modules) are present and connected
                                     •  check zone selectivity connections
                                     •  check the MOE-E stored energy operating mechanism
                                     •  check the circuit breaker status by means of AUP if the CB is a withdrawable version
                                           NOTE: the limitations and notes given for each point in the respective paragraphs are

              Maintenance schedule The frequency with which Ekip Touch maintenance is scheduled differs, depending on the conditions in
                                    the installation site:
                                                                                  Dusty environments
                                                  Standard environments
                                                                                  (level of dust measured > 1 mg / m3)
                                     Frequency of   One year or 2000 operations or after   Every six months or 1000 operations or
                                     maintenance  tripping due to short circuit   after a short-circuit trip


                                    By activating and using Predictive Maintenance in ABB Ability (EDCS) on the specific switch, you can
                                    suggest a different maintenance frequency. (link).
