General safety instructions and application notes for Lenze drive controllers
Transport, storage
Follow the instructions on transport, storage and correct handling.
Observe the climatic conditions (see if necessary chapter "Technical data").
Installation
You must install and cool the drive controller in accordance with the regulations
in the related documentation.
Ensure the device is handled carefully and avoid mechanical overload. Do not
bend components during transport and handling or change isolation distances.
Do not touch any electronic components or contacts.
Drive controllers contain electrostatic sensitive devices that can easily be
damaged in case of improper handling. Do not damage or destroy any electrical
components, as you may harm your health in the process!
Electrical connection
When working on live drive controllers, observe applicable health and safety
regulations (e.g. VBG 4).
Undertake electrical installation in accordance with the applicable regulations
(e.g. cable cross-sections, fusing, protective earth connection). The
documentation contains additional instructions.
The documentation contains instructions for EMC-compliant installation
(shielding, earthing, layout of filters and laying cables). Also follow these
instructions for CE marked drive controllers. The manufacturer of the system or
the machine is responsible for compliance with the limits in relation to EMC law.
To comply with the limits for radiated emissions in the place the device is
installed, the drive controller must be installed in a housing (e.g. control
cabinet). The housing must facilitate an EMC-compliant layout. Pay particular
attention, e.g. that switch cabinet doors are connected metallically to the
housing all round if possible. Openings or break-outs on the housing are to be
reduced to a minimum.
Lenze drive controllers can cause DC currents in the PE conductor. If a residual
current device (RCD) is used for protection against direct or indirect physical
contact, only a residual current device (RCD) of type B is allowed on the power
supply side of the drive controller. Otherwise a different protective measure
must be used, e.g. isolation from the surroundings using double insulation, or
reinforced insulation, or isolation from the supply system using a transformer.
