Qualified Electrical Personnel
Only qualified electrical engineering personnel may commission and operate the equipment (module, de-
vice)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 commis-
sion,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 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 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.
