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.

emissions of light, noise, particles, gases, etc. can occur inside and outside the inverter,
e.g.:
– Component malfunctions
– Software errors
– Operating and/or ambient conditions outside of the specification
– External influences / damage
Inverters of the Open Type / IP20 degree of protection must be installed in a metal control
cabinet (or protected by another equivalent measure) such that the contact with fire inside
and outside the inverter is not possible.
– Component malfunctions
– Influence of electrostatic charging
– Induction of voltages in moving motors
– Operating and/or ambient conditions outside of the specification
– Condensation / conductive contamination
– External influences / damage
