General safety and application notes for Lenze controllers

EDS84ASC552 EN 6.0
Electrical connection
When working on live controllers, observe the applicable national regulations for the
prevention of accidents (e.g. VBG 4).
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.
This documentation contains information on installation in compliance with EMC
(shielding, earthing, filter, and cables). These notes must also be observed for CE−marked
controllers. The manufacturer of the system is responsible for compliance with the limit
values demanded by EMC legislation. The controllers must be installed in housings (e.g.
control cabinets) to meet the limit values for radio interferences valid at the site of
installation. The housings must enable an EMC−compliant installation. Observe 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.
Lenze controllers can cause a DC current in the PE conductor. If a residual current device
(RCD) is used for protection in the event of direct or indirect contact, a residual current
device (RCD) of type B must be used on the supply side of the controller in case of a
three−phase controller supply. Otherwise, a different protective measure must be taken,
e.g. separation from the environment through double or reinforced insulation or
separation from the supply system by means of a transformer.
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). The controllers can be adapted to
your application. Please observe the corresponding information given in the
documentation.
After the controller has been disconnected from the supply voltage, all live components
and power connections must not be touched immediately because capacitors can still be
charged. Please observe the corresponding stickers on the controller.
All protection covers and doors must be shut during operation.
Notes for UL−approved systems with integrated controllers:
UL warnings are notes that
only apply to UL systems. The documentation contains special UL notes.
Safety functions
Special controller variants support safety functions (e.g. "safe torque off", formerly "safe
standstill") according to the requirements of appendix I No. 1.2.7 of the EC Directive
"Machinery" 98/37/EC, EN 954−1 category 3 and EN 1037. Strictly observe the notes on the
safety functions given in the documentation on the respective variants.
Maintenance and servicing
The controllers do not require any maintenance if the prescribed operating conditions are
observed.
Disposal
Recycle metal and plastic materials. Ensure professional disposal of assembled PCBs.
The product−specific safety and application notes given in these instructions must be
observed!
