General safety and application notes for Lenze controllers
Transport, storage
Please observe the notes on transport, storage, and appropriate handling.
Observe the climatic conditions according to IEC/EN 60721.
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.
The documentation contains information on the EMC-compliant installation (shielding,
earthing, arrangement of filters and passing of the cables). Also observe these notes for
CE-labelled controllers. The manufacturer of the system or machine is responsible for the
compliance with the limit values required by EMC legislation. In order to comply with the

limit values for radio interference, which are applicable at the installation location, you
have to mount the controllers into housings (e. g. control cabinets). The housings have to
provide for an EMC-compliant structure. In particular observe that for instance control
cabinet doors preferably are connected metallically to the housing in a circumferential
manner. Housing openings or cutouts are to be reduced to a minimum.
In the case of a malfunction (short circuit to frame or earth fault), Lenze controllers can
cause a DC residual current in the protective conductor. If an earth-leakage circuit breaker
(residual current device) is used as a protective means in the case of indirect contact, only
an e.l.c.b. of type B may be used on the current supply side. Otherwise, another protective
measure such as separation from the environment by double or reinforced insulation or
disconnection from the mains by means of a transformer must be implemented.
