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 EN 50178.
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 notes about EMC-compliant installation (shielding, earthing,
arrangement of filters and routing of cables). Observe these notes also for CE-marked drive
controllers. The manufacturer of the system or machine is responsible for adhering to the
limit values demanded in conjunction with EMC regulations. To adhere to the limit values
for radio interference emissions at the installation site, you must install the drive
controllers in housings (e.g. control cabinet). The housings must allow for EMC-compliant
assembly. In particular, ensure that the control cabinet doors are metallically connected to
the housing with respect to their circumference. Reduce openings or breakthroughs of the
housing 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 beaker
(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 through double or reinforced
insulation or disconnection from the mains by means of a transformer must be used.
