General safety and application notes for Lenze controllers

MA 13.1002 DE−EN DE/EN 1.1
Electrical connection
When working on live controllers, the valid regulations for the prevention of
accidents (e.g. VBG 4) must be observed.
The electrical installation must be carried out according to the appropriate
regulations (e.g. cable cross/sections, fuses, PE connection). Additional
information can be obtained from the documentation.
The documentation contains information concerning installation in
compliance with EMC (shielding, earthing, filter arrangement, and cable
installation). These notes must also be observed for CE−marked controllers. The
manufacturer of the system or machine is responsible for ensuring compliance
with the limit values demanded by the EMC legislation. The controllers must be
installed in housings (e.g. control cabinets) to comply with the limit values for
radio interferences valid at the site of installation. The housings must enable an
EMC−compliant installation. Make sure in particular that e.g. the control cabinet
doors have a circumferential metal connection to the housing. Reduce housing
openings and cutouts to a minimum.
Operation
If necessary, systems including controllers must be equipped with additional
monitoring and protection devices according to the valid safety regulations (e.g.
law on technical equipment, regulations for the prevention of accidents). You
are allowed to adapt the controllers to your application. Please observe the
corresponding information given in the documentation.
After the controller has been disconnected from the voltage supply, all live
components and power connections must not be touched immediately because
capacitors can still be charged.
All protection covers and doors must be kept shut during operation.
Maintenance and servicing
The controllers do not require any maintenance if the prescribed conditions of
operation are observed.
If the ambient air is polluted, the cooling surfaces of the controller may
contaminate, or the air vents of the controller may be blocked. Therefore, the
cooling surfaces and air vents must be cleaned periodically under these
operating conditions. Do not use sharp or pointed tools for this purpose!
Waste disposal
Recycle metal and plastic materials. Assembled PCBs must be disposed of
professionally.
The product−specific safety and application notes given in these instructions
must be observed!
