The five safety rules for electrical work
The European standard EN 50110‑1:2023 "Operation of electrical installations" prescribes
safety rules for work on and in electrical installations. To ensure the safety of persons and
property in accordance with the standards, always comply with the following safety rules.
Securing an electrical system before starting work
Before starting work on and in electrical installations, apply the following five safety rules:
1. Disconnect at electric distributor
2. Secure against reconnection at electric distributor
3. Verify there is no voltage on the electrical distribution board and the workstation.
4. Ground and short-circuit at the electric distributor
5. Erect barriers around or cover adjacent live parts
Prepare to switch on again after work is finished
After finishing and checking the work, prepare the restart as follows:
• Inform persons no longer required that the work is completed and no further work is
permitted.
• Withdraw persons who are no longer required.
• Remove all tools, equipment and aids that have been used.
Switch on the electrical system again
After finishing the work, rescind the protective measures and switch the system on again:
1. Remove the short-circuit.
2. Remove the grounding.
3. Remove covers or barriers.
4. Remove the fuse to prevent the system from being switched on again.
5. Reconnect the system to the power supply.
2.4.4
Electric shock due to lack of grounding
If the protective conductor connection is missing or incorrectly connected, high voltages may
be present on exposed parts. Touching the parts can lead to severe injuries or death. To
ground the charging station, connect the protective conductor in conformance with
regulations.
For more information on connection, refer to the section "Connecting the charging station
