This manual does not constitute a complete catalog of all safety measures required for
operating the respective equipment (module, device), since special operating conditions
may require additional measures. However, it does contain notes which must be adhered
to for your own personal safety and for avoiding property damage. These notes are high-
lighted with a warning triangle and different keywords indicating different degrees of dan-
ger:
Warning
means that death, severe injury or substantial property damage may occur if the appropri-
ate safety measures are not taken.
Caution
means that minor injury or property damage may occur if the appropriate safety measures
are not taken.
Qualified Personnel
Commissioning and operation of the equipment (module, device) described in this manual
must be performed by qualified personnel only. In the sense of the safety notes contained
in this manual, qualified personnel are those persons who are authorized to commission,
release, ground and tag devices, systems and electrical circuits in accordance with safety
standards.
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.
Correct and safe operation of the product requires adequate transportation, storage, instal-
lation and mounting as well as appropriate use and maintenance.
During operation of electrical equipment, it is unavoidable that certain parts of this equip-
ment are carrying dangerous current. Severe injury or property damage may occur if the
appropriate measures are omitted:
•
Before making any connections at all, ground the equipment at the PE terminal.
•
Hazardous voltages may be present on all switching components connected to the
power supply.
•
Even after the supply voltage has been disconnected, hazardous voltages may still be
present in the equipment (capacitor storage).
•
Equipment with current transformer circuits may not be operated while open.
The limit values indicated in the manual or the operating instructions must not be exceeded;
this also applies to testing and commissioning.
