Notes on Safety
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. � Comply with all instructions, in order to avoid death or severe injuries.

! WARNING
WARNING 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.

! CAUTION
CAUTION means that medium-severe or slight injuries can occur if the specified measures are not taken. � Comply with all instructions, in order to avoid moderate or minor injuries.

NOTICE
NOTICE means that property damage can result if the measures specified are not taken. � Comply with all instructions, in order to avoid property damage.

i

NOTE Important information about the product, product handling or a certain section of the documentation

which must be given 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.
