Page 33: Maintenance
Maintenance Maintenance The stability and function of the BKRS walkable cable tray systems and the conveyor system trays can be impaired by external influences, such as damage or machine vibrations. Loose connection elements must be retightened and damaged parts replaced. In addition, we recommend regular checks to see if the con- nection to the overall equipotential bonding is still intact. - Page 34 OBO Bettermann Holding GmbH & Co. KG P.O.
