✧Comply with all instructions, in order to avoid property damage.
NOTE
Important information about the product, product handling or a certain section of the documentation which
must be given particular attention.
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.

Typographic and Symbol Conventions
The following text formats are used when literal information from the device or to the device appear in the text
flow:
Parameter Names
Designators of configuration or function parameters which may appear word-for-word in the display of the
device or on the screen of a personal computer (with operation software DIGSI), are marked in bold letters in
monospace type style. The same goes for the titles of menus.
1234A
Parameter addresses have the same character style as parameter names. Parameter addresses contain the
suffix Ain the overview tables if the parameter can only be set in DIGSI via the option Display additional set-
tings.
Parameter Options
Possible settings of text parameters, which may appear word-for-word in the display of the device or on the
screen of a personal computer (with operation software DIGSI), are additionally written in italics. This also
applies to header bars for selection menus.
“Messages”
Designators for information, which may be output by the relay or required from other devices or from the switch
gear, are marked in a monospace type style in quotation marks.
Deviations may be permitted in drawings and tables when the type of designator can be obviously derived from
the illustration.
