When working on live controllers, observe the applicable national
regulations for the prevention of accidents (e.g. VBG 4).
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 installation according to
EMC (shielding, earthing, arrangement of filters, and installation of the
cables). Also observe this information with regard to drive controllers
labelled with CE marking. The manufacturer of the system or machine is
responsible for the compliance of the limit values required in connection
with EMC legislation. In order to observe the limit values for radio
interference emissions effective at the installation site, you have to mount
the drive controllers into housings (e. g. control cabinets). The housings have
to enable an EMC−compliant structure. Particularly observe that, for
instance, control cabinet doors preferably are metallically connected to the
housing in a circumferential manner. Reduce openings or apertures through
the housing to a minimum.
Lenze controllers can cause a DC current in the PE conductor. If a residual
current device (RCD) is used for the protection in the case of direct or indirect
contact on a three−phase supplied controller, only one residual current
device of type B is permissible on the current supply side of the controller. If
the controller is supplied with one phase, also a residual current device (RCD)
of type A may be used. Apart from the use of a residual current device (RCD)
also other protective measures can be used, like for instance isolation from
the environment by double or reinforced insulation or isolation from the
supply system by a transformer.
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 controllers can be adapted to your application. Please
observe the corresponding information given in the documentation.
After the controller has been disconnected from the supply voltage, 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.
Notes for UL−approved systems with integrated controllers: UL warnings are
notes that only apply to UL systems. The documentation contains special UL
notes.
Special controller variants support safety functions (e.g. "safe torque off",
formerly "safe standstill") according to the requirements of appendix I
No. 1.2.7 of the EC Directive "Machinery" 98/37/EC, EN 954−1 category 3 and
EN 1037. Strictly observe the notes on the safety functions given in the
documentation on the respective variants.
The controllers do not require any maintenance if the prescribed operating
conditions are observed.
Recycle metals and plastics. Dispose of printed circuit board assemblies
according to the state of the art.
The product−specific safety and application notes given in these instructions
