• Never rely solely on the response of the monitoring function to
avert danger. Until the installed monitors become effective, it
must be assumed that the drive movement is faulty, with its
action being dependent on the control unit and the current
operating condition of the drive. Perform maintenance work,
modifications, and attachments outside the danger zone
defined by the movement range.
• To avoid accidents and/or material damage, human access to
the movement range of the machine must be restricted. Limit/
prevent accidental access for people in this area due through
technical safety measures. The protective cover and protective
fence must be rigid enough to withstand the maximum possible
movement energy. EMERGENCY STOP switches must be easily
and quickly accessible. Before starting up the machine or
automated system, check that the EMERGENCY STOP system is
working. Prevent operation of the machine if this protective
equipment does not function correctly.
2.12.4 Protection against electric shock
Work on electrical equipment
Touching live parts may result in death.
• Work on the electrical equipment may only be carried out by
qualified electricians in accordance with the electrical
engineering regulations.
• Lay electrical cables properly, e. g. in a cable duct or a cable
bridge. Observe standards.
• Before connecting or disconnecting electrical cables, switch off
the power supply and check that the cables are free of voltage.
Secure the power supply against being switched on again.
• Before switching on the product, check that the protective
earth conductor is correctly attached to all electrical
components according to the wiring diagram.
• Check whether covers and protective devices are fitted to
prevent contact with live components.
• Do not touch the product's terminals when the power supply is
switched on.
