1.1 Notes on possible severe personal injury
DANGER
!
Risk of fatal injury due to the ignition of an explosive atmosphere.
Incorrect installation, operation or maintenance of the position transmitter in potentially
explosive atmospheres may lead to ignition of the atmosphere and ultimately to death,
even with a harmless supply voltage.
ÎFormountingandelectricalinstallationinhazardousareas,observetheexplosion
protection approvals as well as the relevant electrotechnical regulations and the
accidentpreventionregulationsthatapplyinthecountryofuse.EN60079-14
applies in Europe.
ÎDo not connect the electrical supply before mounting is completed.
ÎInstallation, operation or maintenance of the position transmitter must only be
performedbypersonnelwithqualicationsaccordingtoClause4.5ofIEC60079-14

Risk of fatal injury as a result of electrostatic discharge at the device.
An electric spark generated by electrostatic discharge may lead to ignition of a potential-
ly explosive atmosphere and cause death.

1.2 Notes on possible personal injury
WARNING
!
Crush hazard arising from moving parts on the valve and actuator.
Control valves contain moving parts (actuator and plug stem), which can injure hands or
ngersifinsertedintothevalve.
ÎDo not touch any moving valve parts while the control valve is in operation.
ÎBefore performing any mounting or installation work on the position transmitter, put the
control valve out of operation by disconnecting and locking the supply and control
signal.
Incorrect electrical connection will render the explosion protection unsafe.
ÎAdhere to the terminal assignment.
ÎDo not undo the enameled screws.
