Safety instructions
General safety and application notes for Lenze controllers
Electrical connection
When working on live inverters, observe the applicable national regulations for the
prevention of accidents.
Carry out the electrical installation according to the relevant regulations (e. g. cable
cross−sections, fusing, connection to the PE conductor). Additional notes are included in
the documentation.
This documentation contains information on installation in compliance with EMC
(shielding, earthing, filter, and cables). These notes must also be observed for CE−marked
controllers. The manufacturer of the system is responsible for compliance with the limit
values demanded by EMC legislation. 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 have a circumferential metal connection to
the housing. Reduce housing openings and cutouts to a minimum.
Lenze controllers may cause a DC current in the PE conductor. If a residual current device
(RCD) is used for protection against direct or indirect contact for a controller with
three−phase supply, only a residual current device (RCD) of type B is permissible on the
supply side of the controller. If the controller has a single−phase supply, a residual current
device (RCD) of type A is also permissible. Apart from using a residual current device (RCD),
other protective measures can be taken as well, e.g. electrical isolation by double or
reinforced insulation or isolation from the supply system by means of a transformer.
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). You are allowed to adapt the
controllers 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 terminals must not be touched immediately because capacitors can still be
charged. Please observe the corresponding stickers on the controller.
Keep all protective covers and doors closed during operation.
Safety functions
Certain controller versions support safety functions (e.g. "Safe torque off", formerly "Safe
standstill") according to the requirements of the EC Directive 2006/42/EC (Machinery
Directive). The notes on the integrated safety system provided in this documentation must
be observed.
Maintenance and servicing
The controllers do not require any maintenance if the prescribed conditions of operation
are observed.
