Safety Information

This manual is not a complete index of all safety measures required for operation of the equipment (module, device). However, it comprises important information that must be noted for purposes of personal safety, as well as in order to avoid material damage. Information is highlighted and illustrated as follows according to the degree of danger.

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 medium-severe or slight injuries can occur if the specified measures are not taken.

✧ Comply with all instructions, in order to avoid medium-severe or slight injuries.

NOTICENOTICE means that material damage can result if the measures specified are not taken.

✧ Comply with all instructions, in order to avoid material damage.

NOTE

Important information about the product, product handling, or a certain section of the documentation, which must 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 people who can demonstrate technical qualifications as electrical technicians. These persons may commission, iso-late, ground and label devices, systems and circuits according to the standards of safety engineering.

Use as Prescribed

The equipment (device, module) may only be used for such applications as set out in the catalogs and the tech-nical description, and only in combination with third-party equipment recommended and approved by Siemens.

Problem-free and safe operation of the product depends on the following:

• Proper transport

• Proper storage, setup, and installation

• Proper operation and maintenance

When electrical equipment is operated, hazardous voltages are inevitably present in certain parts. If proper action is not taken, death, severe injury, or material 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).

• Equipment with exposed current-transformer circuits must not be operated. Before disconnecting the equipment, ensure that the current-transformer circuits are short-circuited.

• The limit values stated in the document may not be exceeded. This must also be considered during testing and commissioning.
