2.5  ESD (Electro Static Discharge) protective measures 
 
 
CAUTION 
 
Danger for electronic components due to electrostatic discharge. 
Improper handling of printed circuit boards or components can cause damages that 
lead to complete failures or sporadic errors. 
During installation and repair of the device, the ESD protective measures must be 
considered. 
Please consider the following guidelines before the installation or maintenance of 
the device: 
•  If you deal with electronic components, always carry a wristband for the 
protection against electrostatic discharge. Connect one part of the wristband 
with a discharge socket or an unvarnished grounded metal component. 
•  Only touch the printed circuit boards at the edges. Do not touch the printed 
circuit board itself or the connector.  
•  Place all dismantled components on an anti-static surface or in a static-proof 
container.  
•  Avoid contact between printed circuit boards and your clothing. The 
wristband only protects the printed circuit boards against electrostatic 
discharge from the body, but there is still a risk of damage through 
electrostatic discharge from your clothing. 
•  Only transport and dispatch dismantled modules in protective bags.
