General safety and application notes for Lenze controllers
Installation
The controllers must be installed and cooled according to the regulations given in the
corresponding documentation.
Ensure careful handling and avoid mechanical overload. Do not bend any components and
do not change the insulation distances during transport and handling. Electronic
components and contacts must not be touched.
Drive controllers contain electrostatically sensitive components which can easily be
damaged by inappropriate handling. Do not damage or destroy any electrical components
since this could mean hazards to your health!
Electrical connection
When working on live drive controllers, the valid national regulations for the prevention
of accidents (e.g. VBG 4) must be observed.
Carry out the electrical installation in compliance with the corresponding regulations (e.g.
cable cross-sections, fuses, PE connection). More detailed information is given in the
corresponding documentation.
Notes about wiring 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.
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 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 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 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 UL notes.
