not guarantee compliance with the original safety requirements or the material

resistance, and can therefore not be held responsible for any resulting damage.

2. Is the delivery complete or is anything missing? Check the scope of delivery against

your order.

3. Does the nameplate match the ordering information on the delivery note?

4. Are the technical documentation and all other necessary documents provided? If

applicable: are the Safety Instructions (e.g. XA) for hazardous areas provided?
