Transport and storage
Please observe the notes on transport, storage and appropriate handling.
Observe the climatic conditions according to the technical data.
Installation
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!
Electrical connection
When working on live controllers, the valid national regulations for the prevention of
accidents (e.g. VBG 4) must be observed.
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.
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.
Lenze controllers cancause adirect current inthe protective conductor. Ifaresidualcurrent
device (RCD) is used as a protective means in the case of direct or indirect contact, only a
residual current device (RCD) of type B may be used on the current supply side of the
controller. 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.
