  • Page 5: Safety Instructions And Measures

    Therefore, operators must ensure that the actuator is only used in operating conditions that meet the specifications used for sizing the actuator at the ordering stage. In case operators intend to use the actuator in other applications or conditions than specified, contact SAMSON. SAMSON does not assume any liability for damage resulting from the failure to use the de- vice for its intended purpose or for damage caused by external forces or any other external factors. Î Refer to the technical data and nameplate for limits and fields of application as well as possible uses.
  • Page 6 − Eye protection and hearing protection while the actuator is operating. Î Check with the plant operator for details on further protective equipment. Revisions and other modifications Revisions, conversions or other modifications of the product are not authorized by SAMSON. They are performed at the user's own risk and may lead to safety hazards, for example. Fur- thermore, the product may no longer meet the requirements for its intended use.
  • Page 7 Safety instructions and measures Referenced standards, directives and regulations According to the ignition risk assessment performed in accordance with Clause 5.2 of ISO 80079-36, the non-electrical actuators do not have their own potential ignition source even in the rare incident of an operating fault. As a result, they do not fall within the scope of Directive 2014/34/EU. Î For connection to the equipotential bonding system, observe the requirements specified in Clause 6.4 of EN 60079-14 (VDE 0165-1). The Type 3271 and Type 3277 Actuators are partly completed machinery as defined in the Machinery Directive 2006/42/EC or the Directive 2008 No. 1597 Supply of Machinery (Safety) Regulations 2008.
