Electrostatic sensitive devices can be labeled with an appropriate symbol. 
 
Electrostatic sensitive devices (ESD) 
When you touch electrostatic sensitive components, you can destroy them through voltages 
that are far below the human perception threshold. 
If you work with components that can be destroyed by electrostatic discharge, observe the 
ESD Guideline (Page 103). 
Siemens offers products and solutions with Industrial Security functions that support the safe 
operation of equipment, solutions, machines, devices and/or networks. They are important 
components in a comprehensive Industrial Security concept. As a result the products and 
solutions from Siemens are constantly evolving. Siemens recommends obtaining regular 
information regarding product updates. 
For safe operation of Siemens products and solutions appropriate protective measures (e.g., 
cell protection concept) must be taken and each component must be integrated in a 
comprehensive Industrial Security concept, which corresponds with the current state of 
technology. The products of other manufacturers need to be taken into consideration if they 
are also used. You can find addition information on Industrial Security under 
(http://www.siemens.com/industrialsecurity).

Notes on protecting administrator accounts 
A user with administrator privileges has extensive access and manipulation options in the 
system. 
Therefore, ensure there are adequate safeguards for protecting the administrator accounts 
to prevent unauthorized changes. To do this, use secure passwords and a standard user 
account for normal operation. Other measures, such as the use of security policies, should 
be applied as needed.
