Qualified Personnel
Commissioning and operation of the equipment (module, device) as set out in this manual may only be
carried out by qualified personnel. Qualified personnel in terms of the technical safety information as set
out in this manual are persons who are authorized to commission, activate, to ground and to designate

Use as prescribed
The operational equipment (device, module) may only be used for such applications as set out in the cata-
logue and the technical description, and only in combination with third-party equipment recommended or
approved by Siemens.
The successful and safe operation of the device is dependent on proper handling, storage, installation,
operation, and maintenance.
When operating an electrical equipment, certain parts of the device are inevitably subject to dangerous
voltage. Severe personal injury or property damage may result if the device is not handled properly.
Before any connections are made, the device must be grounded to the ground terminal.
All circuit components connected to the voltage supply may be subject to dangerous voltage.
Dangerous voltage may be present in the device even after the power supply voltage has been removed
(capacitors can still be charged).
Operational equipment with open circuited current transformer circuits may not be operated.
The limit values as specified in this manual or in the operating instructions may not be exceeded. This
aspect must also be observed during testing and commissioning.
