3.2 Safety instructions for works on electrical equipment
Work on electrical equipment has to be carried out by qualified electricians only.
The power line connection of the converter must be specified correctly to
prevent overload.
Disconnect the voltage supply before connecting the power line. Only connect
the power line when voltage-free. Do not use the clamp socket for release since
no first-to-mate last-to-break protective ground contact is provided.
Do not work on live active parts of the electrical equipment. When working on
the electrical equipment, observe the following safety regulations:
1. Switch voltage-free.
2. Protect against re-commissioning.
3. Check if voltage-free.
4. Cover live parts.
5. Ground and short-circuit.
In case of faults in the power supply, disconnect the converter immediately.
In case of a short-circuit, there is a danger of sparking and fire.
Use only original fuses with specified current and triggering characteristics!
When a fuse has to be exchanged, first try to detect the cause and clear the fault
before exchanging the fuse.
When work on live parts is necessary, use insulated tools only.
