2.2 Qualified Personnel
The products must only be assembled, installed, programmed, commissioned, maintained, and decommissioned by persons with
proven skills. Persons with proven skills:
Are qualified electrical engineers, or persons who have received training from qualified electrical engineers and are suitably
experienced to operate devices, systems, plant, and machinery in accordance with the general standards and guidelines for
safety technology.
Are familiar with the basic regulations concerning health and safety/accident prevention.
Have read and understood the safety guidelines given in this manual and also the instructions given in the operating guide of
the drive.
Have good knowledge of the generic and specialist standards applicable to the specific application.
2.3 Responsibilities of Users of Safety-related Power Drive Systems PDS(SR)
Users of safety-related Power Drive Systems (PDS(SR)) are responsible for:
Hazard and risk analysis of the application.
Identifying safety functions required and allocating SIL or PLr to each of the functions.
Other subsystems and the validity of signals and commands from these subsystems.
Designing appropriate safety-related control systems (hardware, software, parameterization, and so on).
2.4 Protective Measures
Qualified and skilled personnel must be available for installing and commissioning the safety engineering systems.
Procedure
Install the drive in an IP54 cabinet as per IEC 60529, or in an equivalent environment. In special applications, a higher IP
rating may be necessary.
Ensure short-circuit protection of the cable between terminal 37 and the external safety device according to ISO 13849-2
table D.4.
Install additional measures (for example, a safety holding brake) if external forces influence the motor axis (for example
suspended loads).
