Observing the Five Safety Rules

There are five safety rules that must always be observed to assure not only personal safety, but
to prevent material damage as well. Always obey safety-related labels located on the product
itself and always read and understand each safety precaution prior to operating or working on
the drive.
The five safety rules:
1. Disconnect the system.
2. Protect against reconnection.
3. Make sure that the equipment is de-energized.
4. Apply grounding means.
5. Cover or enclose adjacent components that are still live.
Danger Due to High Voltages
High voltages cause death or serious injury if the safety instructions are not observed or if the
equipment is handled incorrectly.
Potentially fatal voltages occur when this equipment is in operation which can remain present
even after the VFD is switched off.
Ensure that only qualified and trained personnel carry out work on the equipment.
Follow the five safety rules during each stage of the work.
