SAFETY 2.1 SAFETY INSTRUCTIONS 2.1.6 WARNING OF SPECIAL DANGERS ELECTRIC ENERGY Use only original fuses and circuit breakers with the specified current rating. Switch off the machine immediately if trouble occurs in the electrical system. When working with the machine , maintain a safe distance from overhead electric lines. If work is to be carried out close to overhead lines, the working equipment must be kept well away from them. Caution, danger! Check out the prescribed safety distances.
If your machine comes into contact with a live wire do not leave the machine drive the machine out of the hazard zone warn others against approaching and touching the machine have the live wire de-energized do not leave the machine until the damaged line has been safely de-energized. Work on the electrical system or equipment may only be car- ried out by a skilled electrician himself or by specially instructed personnel under the control and supervision of such electrician and in accordance with the applicable electri- cal engineering rules.
If provided for in the regulations, the power supply to parts of machine, on which inspection, maintenance and repair work is to be carried out must be cut off. Before starting any work, check the de-energized parts for the presence of power and ground or short-circuit them in addi- tion to insulating adjacent live parts and elements. The electrical equipment of the machine is to be inspected and checked at regular intervals. Defects such as loose con- nections or scorched cables must be rectified immediately.
Necessary work on live parts and elements must be carried out only in the presence of a second person who can cut off the power supply in case of danger by actuating the emer- gency shut-off or main power switch. Secure the working area with a red-and-white safety chain and a warning sign. Use insulated tools only. Before starting work on high-voltage assemblies and after cutting out the power supply, the feeder cable must be grounded and components such as capacitors short-circuited with a grounding rod. 23
