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 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 about installation in compliance with EMC
(shielding, earthing, filters and cables). These notes must also be observed for CE-marked
controllers. The manufacturer of the system or machine is responsible for the compliance
with the required limit values demanded by the EMC legislation.
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 direct or 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 seperation from the environment through double or
reinforced insulation or disconnection from the mains by means of a transformer must be
used.
Operation
If necessary, system 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 controller can be adapted to
your application. Please observe the corresponding information given in the
documentation.
After a 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. 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 information about UL.
