Electrical connection
When working on live controllers, the valid national regulations for the prevention of accidents
(e.g. VBG 4) must be observed.
Carry out the electrical installation in compliance with the corresponding regulations (e.g. cable
cross−sections, fuses, PE connection). More detailed information is given in the corresponding
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 can cause a DC current in the protective conductor. If a residual current 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.
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). 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 UL systems. The documentation contains special UL notes.
Safety functions
Special controller variants support safety functions (e.g. "safe torque off", formerly "safe standstill")
according to the requirements of Annex 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.
Maintenance and servicing
The controllers do not require any maintenance, if the prescribed conditions of operation are observed.
If the ambient air is polluted, the cooling surfaces of the controller may become dirty or the air vents of
the controller may be obstructed. Therefore, clean the cooling surfaces and air vents periodically under
these operating conditions. Do not use sharp or pointed tools for this purpose!
Waste disposal
Recycle metal and plastic materials. Ensure professional disposal of assembled PCBs.
The product−specific safety and application notes given in these instructions must be observed!
