1.1 Definitions 
These Operating Instructions do not contain all of the detailed information 
for all product types for reasons of transparency. This means that they 
cannot take into account all conceivable situations regarding the 
configuration, operation or service. If you require additional information, 
or if specific problems occur, which are not handled in sufficient detail in 
the Operating Instructions, then you can request the necessary 
information from your local Siemens Office. 
We would also like to point-out, that the contents of the operating 
instructions are neither part of an earlier or existing agreement, statement 
or legal relationship, nor do they change this. All of the contractual 
responsibilities of Siemens AG are specified in the purchase contract 
which includes the complete and exclusively valid warranty. The 
contractual warranty is neither expanded nor restricted by the information 
provided in these Operating Instructions. 
For the purpose of these Operating Instructions and product labels, a 
„Qualified person“ is someone who is familiar with the installation, 
mounting, start-up and operation of the equipment and the hazards 
involved. He or she must have the following qualifications: 
1.  Trained and authorized to energize, de-energize, clear, ground and 
tag circuits and equipment in accordance with established safety 
procedures.
