  • Page 7 Safety instructions and measures Servicing explosion-protected devices If a part of the device on which the explosion protection is based needs to be serviced, the device must not be put back into operation until a qualified inspector has assessed it according to explosion protection requirements, has issued an inspection certificate, or given the device a mark of conformity.

  • Page 8: Notes On Possible Severe Personal Injury

    Safety instructions and measures 1.1 Notes on possible severe personal injury DANGER Risk of fatal injury due to the formation of an explosive atmosphere. Incorrect installation, operation or maintenance of the positioner in potentially explosive atmospheres may lead to ignition of the atmosphere and ultimately to death. Switching the assignment of the electrical terminals may cause the explosion protection to become ineffective.

  • Page 9: Notes On Possible Personal Injury

    Safety instructions and measures 1.2 Notes on possible personal injury WARNING Risk of injury by possible movement of the actuator stem after connecting the signal pressure. Î Do not touch or block the actuator stem. 1.3 Notes on possible property damage NOTICE An incorrect electric signal will damage the positioner.
