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

DANGER

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

²

WARNING

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

²

CAUTION

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

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

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

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,
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 the
technical 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 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 the

•

equipment, ensure that the current-transformer circuits are short-circuited.

The limiting values stated in the document must not be exceeded. This must also be considered during

•

testing and commissioning.
