Safety instructions General safety and application instructions for Lenze controllers 3 3.1 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 Ifnecessary,systemsincludingcontrollersmustbeequippedwithadditional 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”safestandstill”)accordingtotherequirementsofAnnexINo.
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. Theproduct-specificsafetyandapplicationnotesgivenintheseinstructions must be observed! 3.1-2 EDS94SPP101 EN 1.0-12/2005
