Safety instructions
General safety and application notes for Lenze controllers
Installation
The controllers must be installed and cooled according to the instructions given in the
corresponding documentation.
Ensure proper handling and avoid mechanical stress. Do not bend any component and do
not change any insulation distance during transport or handling. Do not touch any
electronic component or contact.
Controllers contain electrostatically sensitive components which can easily be damaged
by inappropriate handling. Do not damage or destroy any electrical component since doing
so might endanger your health!
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!
