Personnel Qualified in Electrical Engineering
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) must not be used for any other purposes than those described in the Catalog
and the Technical Description. If it is used together with third-party devices and components, these must be
recommended or approved by Siemens.
If the device is not used in accordance with the Product Information and this manual, the scheduled protection
is impaired.
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 ac-
tion 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).
• Equipment with exposed current transformer circuits must not be operated. Prior to 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.
