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.

Possible electrostatic energy

Components or assembly groups may become electrostatically
charged. When the electrostatic charge is touched, the discharge
may trigger a shock reaction leading to injuries.
• The operator must ensure that all components and assembly

groups are included in the local potential equalisation in
accordance with the applicable regulations.

• While paying attention to the actual conditions of the working

environment, the potential equalisation must be implemented
by a specialist electrician according to the applicable
regulations.

• The effectiveness of the potential equalisation must be verified

by executing regular safety measurements.
