Residual Risks During The Operation Of Electric Motors - Siemens SINAMICS V90 Operating Instructions Manual

Note
The components must be protected against conductive contamination (e.g. by installing them
in a control cabinet with degree of protection IP54 according to IEC 60529 or NEMA 12).
Assuming that conductive contamination at the installation site can definitely be excluded, a
lower degree of cabinet protection may be permitted.
For more information about residual risks of the components in a drive system, see the
relevant sections in the technical user documentation.
1.1.5

Residual risks during the operation of electric motors

The motors may be operated only when all protective equipment is used.
Motors may be handled only by qualified and instructed qualified personnel that knows and
observes all safety instructions for the motors that are explained in the associated technical
user documentation.
When assessing the machine's risk in accordance with the respective local regulations (e.g.,
EC Machinery Directive), the machine manufacturer must take into account the following
residual risks emanating from the control and drive components of a drive system:
1. Unintentional movements of driven machine components during commissioning,
operation, maintenance, and repairs caused by, for example,
– Hardware and/or software errors in the sensors, control system, actuators, and cables
– Response times of the control system and of the drive
– Operation and/or environmental conditions outside the specification
– Condensation/conductive contamination
– Errors during the assembly, installation, programming and parameterization
– Use of wireless devices/mobile phones in the immediate vicinity of the control system
– External influences/damage
2. In case of failure, unusually high temperatures inside and outside the motor, including
open fire as well as the emission of light, noise, particles, gases, etc. can result, for
example in
– Component failure
– Software errors in converter operation
– Operation and/or environmental conditions outside the specification
– External influences/damage
