Operating personnel must read and understand these mounting and operating instructions as well as the specified hazard statements, warning and caution notes. Furthermore, the operat- ing personnel must be familiar with the applicable health, safety and accident prevention regulations and comply with them. Referenced standards, directives and regulations Devices with a CE marking fulfill the following requirements of the Directives: − Type 3767-0: 2014/30/EU, 2011/65/EU − Type 3767-1/-8: 2014/30/EU, 2014/34/EU, 2011/65/EU Devices with an EAC marking fulfill the requirements of the Regulation TR CU 020/2011.

Safety instructions and measures Referenced documentation The following documents apply in addition to these mounting and operating instructions: − The mounting and operating instructions of the components on which the positioner is mounted (valve, actuator, valve accessories etc.). 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 positioner in potentially explo- sive atmospheres may lead to ignition of the atmosphere and ultimately to death.
Safety instructions and measures WARNING Intrinsic safety rendered ineffective in intrinsically safe devices. Every time the positioner is operated, even not within the plant (e.g. during mainte- nance, calibration and work on equipment), it must be ensured that the conditions for intrinsically safe circuits are observed.
Safety instructions and measures 1.4 Special instructions concerning explosion protection Equipment for use in zone 2/zone 22 Î In equipment operated according to type of protection Ex nA II (non-sparking equip- ment) according to EN 60079-15: 2003, circuits may be connected, interrupted or switched while energized only during installation, maintenance or repair. Î Equipment connected to energy-limited circuits with type of protection Ex nL accord- ing to EN 60079-15:2003 may be switched under normal operating conditions. Î The maximum permissible values specified in the statement of conformity or its ad- denda apply when interconnecting the equipment with energy-limited circuits in type of protection Ex nL IIC. Servicing explosion-protected devices Î Observe the following for servicing equipment in a section relevant for explosion pro- tection: − The equipment must not be put back into operation until a qualified inspector has assessed the equipment according to explosion protection requirements, has is-...
