You can then choose whether to plug in the other 
peripheral ports at this point or do it later depending 
on  the  actual  location  of  the  device  or  level  of 
comfort for performing such operation.

Remeber to plug in the protective caps for the 
unused SFP. 

3. 

Once the plate has been firmly put in place, proceed 
to  mount  the  whole  device  as  shown  in  (Fig. 
3).Proceed  to  (Fig.  4)  if  you  want  to  remove  the 
device from DIN-Rail. 

4. 

Next we can then proceed to connect the device to 
the LAN (switch or PC, depending on the case), take 
care on using the RJ-45 connector; after this we can 
then proceed to the device’s settings

5. 

If you have purchased the wall mount kit, 
proceed to place the screws on the back 
of the device as show in (Fig. 1).

1. 

2.  Although  internal  grounding  has  been 

done  inside,  in  order  to  ensure  overall 
maximum  performance  and  protect  your 
device, it is still strongly advised to ground 
the  device  properly;  hazardous  ESD  can 
come into contact and damage your 
equipment. On the power terminal block, 
there is a terminal for Frame Ground, you 
can choose whether to connect it to the 
grounding or you may opt to connect to 
the grounding screw next to the terminal 
block ( the one chosen should be connect-
ed at all times ) (Fig. 2)
