NOTICE

 

Read the safety instructions at the beginning of this document carefully before you 
start with the hardware installation!

 

 

 

DANGER

 

Hazardous Voltage - Risk of electric shock due to unintentional contact with uninsulated 
live parts with high voltages inside of the system into which the CPCI-CAN/200

 

is to be 

integrated.   

 

 

   

Disconnect all hazardous voltages (mains voltage) before opening the system.  
Never carry out work while power supply voltage is switched on! 
Ensure the absence of voltage before starting any electrical work. 

 

 

NOTICE

 

Electrostatic discharges may cause damage to electronic components.  

 

  

   

To avoid this, please discharge the static electricity from your body by touching the 
metal case of the CompactPCI system 

before

 you touch the CPCI-CAN/200. 

Furthermore, you should prevent your clothes from touching the CPCI-CAN/200, 
because your clothes might be electrostatically charged as well.

 

 
 

Procedure:

 

 

1.  Switch off your CompactPCI system and all connected peripheral devices (monitor, printer, 

etc.). 

2.  Discharge your body as described above. 
3.  Disconnect the system from the mains.  

Make sure that no risk arises from the system into which the CPCI-CAN/200 shall be 
inserted. 

 

 
 

DANGER

 

Hazardous Voltage 
Risk of electric shock due to unintentional contact with uninsulated live parts with high 
voltages. 

 

 

 

 
 

 

 

Disconnect all hazardous voltages (mains voltage) before opening the system.  
If the system does not have a flexible mains cable, but is directly connected to 
mains, disconnect the power supply via the safety fuse and make sure that the fuse 
cannot switch on again unintentionally (e. g. with caution label). 
Ensure the absence of voltage before starting any electrical work.  
Cover or block off adjacent live parts. 

 

4. 

 
Open the case if necessary. 

5.  Insert the CPCI-CAN/200 board into the selected CompactPCI slot. The CAN module can be 

inserted into any 3U-slot.  
- Carefully push the board back until it snaps into place.  
- Attach the module by means of the front panel screws. 

6.  Close the system's case again. 
7.  Fix the module.
