3.1
Applications
The drive is a medium-voltage drive for phase-rotation-controlled machines. The drive is a
single drive designed for applications with a quadratic, constant load characteristic and no
regenerative feedback. Typical applications include pumps, fans, compressors, extruders,
mixers, and mills.
3.2
Safety concept
The device and its associated components are subject to an extensive safety concept. When
used properly, the security concept guarantees safe installation, safe operation as well as safe
service and maintenance.
The safety concept encompasses safety components and functions to protect the device and
operators. The device is also equipped with monitoring functions to protect external
components.
The device operates safely when the interlock and protection systems are functioning properly.
Nevertheless, there are areas that are hazardous for personnel and that cause material
damage if the safety information of all the instructions and the labels on the device are not
strictly complied with.
3.2.1
Safety components and functions
The following safety components and functions are installed to protect personnel:
● The make-proof grounding switch for grounding the voltage DC link.
● The electromechanical door interlocking system prevents access to the power unit while
operational. The doors cannot be opened until the grounding switch has been closed. The
door for the control section, however, can be opened for monitoring purposes even during
operation.
● The electromechanical interlock system for the make-proof grounding switch prevents the
make-proof grounding switch from closing for the voltage DC link. The make-proof
grounding switch can only be closed if the circuit-breaker is open and the DC link has been
completely discharged.
● The EMERGENCY OFF mushroom pushbutton in the cabinet door is a pushbutton with
mechanical interlock system for EMERGENCY OFF, Stop Category 0 (standard).
