50 EDKLCFH3024−XPM DE/EN 6.0
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 components and do
not change any insulation distances during transport or handling. Do not touch any
electronic components and contacts.
Controllers contain electrostatically sensitive components, which can easily be damaged
by inappropriate handling. Do not damage or destroy any electrical components since this
might endanger your health!
Electrical connection
When working on live controllers, the valid national 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.
Notes about installation according to EMC regulations (shielding, earthing, filters and
cable routing) are included in the documentation. These notes also apply to CE−marked
controllers. The compliance with limit values required by the EMC legislation is the
responsibility of the manufacturer of the machine or system.
Lenze controllers can cause a direct current in the protective conductor. If a residual current
device (RCD) is used as a protective means in the case of direct or indirect contact, only a
residual current device (RCD) of type B may be used on the current supply side of the
controller. Otherwise, another protective measure such as separation from the
environment through double or reinforced insulation or disconnection from the mains by
means of a transformer must be used.
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 a 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.
Note 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 Annex 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.
