9. PREVENTIVE MAINTENANCE
It is recommended to verify at least once a year the tightening torque of all connections and to operate the product in a full
operating cycle (I
– 0 – II – 0 – I: Auto and Manual) as well as tightening the door mounting clips and testing the LED’s with the
lamp test button when applicable.
In case of upstream protection tripping (fuse protection / Circuit breakers) make sure that the ATS remains functional by doing
a functional test with the RTSE connected to the controller.
To clean the front face of the equipment, use a soft cloth with water and non-abrasive liquids.
Note: Maintenance should be planned carefully and carried out by qualified and authorized personnel. Consideration of the
critical level and application where the product is installed should form an essential and integral part of the maintenance plan.
Good engineering practice is imperative whilst all necessary precautions must be taken to ensure that the intervention (whether
directly or indirectly) remains safe in all aspects.
Maintenance operation should be done by trained and qualified personnel using the
appropriate protection equipment.
