Commissioning

All Schmid AG energy solutions products are normally taken into operation by our
trained staff.
An essential part of the commissioning process includes the instruction of the future
equipment operators.
The equipment operators must be present during commissioning. The personnel
should be familiar with the instruction manual prior to commissioning. The instruction
of the equipment operators is part of the acceptance of the system.
