Direct mounting
NOTICE
The term "direct mounting" is used if the top clearance b described in chapter Mounting
dimensions, clearances, and assembly type [Page 54] is not complied with, e.g. if the soft
starter is mounted directly on a motor starter protector (e.g. 3RV2) using a link module (e.g.
3RV29).

Installation requirements
Degree of protection IP00
CAUTION
The SIRIUS 3RW30 / 3RW40 soft starters conform to the IP00 degree of protection.
The devices must be installed in control cabinets with the IP54 degree of protection (pollution
degree 2), taking account of the ambient conditions.
Make sure no liquids, dust, or conductive objects can get inside the soft starter. The soft
starter produces waste heat (power loss) while it is operating (refer to chapter Technical data
[Page 121]).
The permissible switching frequency values can vary according to the selected assembly
type. For information about factors and how to determine the new switching frequency, refer
to chapter Configuration [Page 73].
Provide adequate cooling at the place of installation to prevent the switching device from
overheating.
