Safety Information

This manual is not a complete index of all safety measures required for operation of the equipment (moduleor device). However, it contains important information that must be followed for personal safety, as well as toavoid physical damage. Information is highlighted and illustrated as follows according to the degree ofdanger.

! DANGERDANGER means that death or severe injury will result if the measures specified are not taken.

Comply with all instructions in order to avoid death or severe injuries.

! WARNINGWARNING means that death or severe injury may result if the measures specified are not taken.

Comply with all instructions in order to avoid death or severe injuries.

! CAUTIONCAUTION means that moderately severe or slight injuries can occur if the specified measures are nottaken.

Comply with all instructions in order to avoid moderate or minor injuries.

Preface


NOTICENOTE means that property damage can result if the measures specified are not taken.

Comply with all instructions in order to avoid property damage.

iiNOTE

Important information about the product, product handling or a certain section of the documentation, whichmust be given particular attention.

Qualified Electrical Engineering Personnel

Only qualified electrical engineering personnel may commission and operate the equipment (module, device)described in this document. Qualified electrical engineering personnel in the sense of this manual are peoplewho can demonstrate technical qualifications as electrical technicians. These persons may commission,isolate, ground and label devices, systems and circuits according to the standards of safety engineering.

Proper Use

The equipment (device, module) may be used only for such applications as set out in the catalogs and thetechnical description, and only in combination with third-party equipment recommended and approved bySiemens.Problem-free and safe operation of the product depends on the following: Proper transport Proper storage, setup and installation Proper operation and maintenanceWhen electrical equipment is operated, hazardous voltages are inevitably present in certain parts. If properaction is not taken, death, severe injury or property damage can result. The equipment must be grounded at the grounding terminal before any connections are made. All circuit components connected to the power supply may be subject to dangerous voltage. Hazardous voltages may be present in equipment even after the supply voltage has been disconnected

(capacitors can still be charged).

Operation of equipment with exposed current-transformer circuits is prohibited. Before disconnecting theequipment, ensure that the current-transformer circuits are short-circuited.

The limiting values stated in the document may not be exceeded. This must also be considered duringtesting and commissioning.
