1 Device series DS71.9 Maintenance and inspectionDS7 Soft starter 09/16 MN03901001Z-EN www.eaton.com 23If installed in machines, the soft starters must not be commissioned until ithas been determined that the corresponding machines comply with thesafety requirements in Machinery Directive 2006/42/EC. Standard EN 60204must be complied with within this context. Commissioning is only permittedif the requirements of the EMC Directive (2014/30/EU) have been observed.The soft starters of the DS7 series meet the requirements of the LowVoltage Directive 2014/35/EU and the product standard EN 60947-4-2.The user is responsible for ensuring that the use of the relevant machines,as well as the corresponding applications, complies with all applicable ECDirectives. Any other usage constitutes improper use.Observe the technical data and connection requirements. These are shownon the rating plate of the soft starter as well as in this documentation.1.9 Maintenance and inspectionDS7 soft starters will be maintenance-free provided that the correspondinggeneral rated operational data, as well as all specific technical data(￫ section 1.7, “Technical data”) for the relevant versions, is observed.However, please note that external factors may have an impact on theoperation and lifespan of DS7 soft starters.We therefore recommend that the devices are checked regularly and thefollowing maintenance measures are carried out at the specified intervals.Table 8: Maintenance measures and maintenance intervalsDS7 soft starters are not designed in such a way as to allow for thereplacement or repair of their individual components or sub-assemblies.￫ At the output of a DS7 soft starter (terminals U, V, W) you mustnot• connect any capacitive load (e.g. phase compensationcapacitors),• do not connect any further soft starters (parallel connectionon output side).Maintenance measures Maintenance intervalClean cooling vents (cooling slits) please enquireCheck the fan function 6 - 24 months (depending on the environment)Filter in the control panel doors(see the manufacturer’s specifications)6 - 24 months (depending on the environment)Check the terminal’s (control signal terminals,power terminals) tightening torquesregularlyCheck connection terminals and all metallic surfaces forcorrosion6 - 24 months; when stored, no more than 12 months later(depending on the environment)Motor cable According to manufacturer specifications, no later than 5 years
