EDSVF9333V EN 3.0-06/2005
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!
When working on live controllers, the valid national regulations for the
prevention of accidents (e.g. VBG 4) must be observed.
The electrical i nstallation 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. The controllers must be installed in housings (e.g.
control cabinets) to meet the limit values for radio interferences valid at the
site of installation. The housings must enable an EMC-compliant
installation. Observe in particular that e.g. the control cabinet doors should
have a circumferential metal connection to the housing. Reduce housing
openings and cutouts 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 through double or reinforced insulation or
disconnection from the mains by means of a transformer must be used.
Ifnecessary, systems including controllers must be equipped withadditional
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 U L systems. The documentation contains special UL
notes.
