Installing and connecting up the LINK 
 
Note 
Only wire up the LINK with the power switched off.
 
Mount the LINK as follows: 
1.  Mount the LINK on the 35 mm DIN rail. 
2.  Connect the turned off power supply to the LINK. See section X80: External power supply 
(Page 27). 
3.  Connect the LINK to Industrial Ethernet via one of the RJ-45 jacks (X1). 
As an alternative you can use bus adapters at X3, that must be plugged in with the power 
turned off. When using bus adapters, the Ethernet interface X1 is inactive.
