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 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
Perform the following inspections:
• 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
the wiring, modules and accessories:
• verification of alarms
• check that the modules (terminal box and external modules) are present and connected
• check zone selectivity connections
• check opening and closing actuators
NOTE: the limitations and notes given for each point in the respective paragraphs are applicable
