Safety Safety • Skilled and trained electricians Due to their educational and professional skills, know-how and experience, and due to their knowledge of the relevant regulations in the field of elec trical engineering, these persons are capable of executing electrical work and recognizing potential hazards independently. • Prior to conducting any maintenance, cleaning or repair work, disconnect the mains supply and secure it against inadvertent switching on. • Do not short-circuit or make fuses inoperable. 2.5 Special hazards This section indicates certain residual risks, which may arise as a result of the risk assessment.
2.6 Safety devices The safety information and warnings given here and in the following chapters of these instructions have to be observed in order to reduce any health ha zards and avoid hazardous situations. Warning! Lethal hazard by non-functional safety devices! Safety devices are provided to ensure a maximum of operational safety. Electric current The multifunctional counter itself does not include any installed safety de vices. These safety devices have to be attached externally. Danger! Lethal hazard of electric shock! Any contact with hazardous live components pre sents a direct lethal hazard. Damages of the insulation or individual compo nents present a potential lethal hazard.
Protect the electrical supply of the multifunctional counter by means of exter nal fuses (see Chapter 10, Technical Data). Whether or not additional safety devices (e.g. emergency-off buttons) have to be provided depends on the general design and construction of the machine or plant. The machine/plant manufacturer shall be responsible for providing such addi tional safety devices in according with his own risk assessment. • In the event of any damage to the insulation, imme diately disconnect the voltage supply and initiate the appropriate repair work. • Any work on the electrical plant has to be carried out by skilled and trained electricians only.
• Before commencing your work on the electrical system, disconnect it from the main supply and check that it no longer carries any live voltages. 16 17
