5.3.2 Method of Operation 
You need at least one LPI-10 for each network segment in order to supply the Lock-
Nodes. 
The LPI-10 (new construction) has 3 terminals for connection to the supply voltage: 
Terminals: 
INPUT AC 230V: 
L1:  230V~ connection 
N:  230V~ connection 
PE:  Potential compensation connection 
OUTPUT BUS: 
NET+: Network cable connection 
NET-:  Network cable connection 
BRIDGE 1 + 2: 
-  For a network with no topological 
structure or with a star-shaped 
structure, bridge the "Bridge 1-2" connection   
-  You are not permitted to bridge this connection if you are using a bus topology. 
5.3.3 Assembly Instructions 
The LPI-10 is intended 
for installation in 
distribution boxes with 
DIN rails. Clamp the 
voltage supplied from 
outside to the 
terminals marked for 
that purpose. 
Depending on the 
structural situation and 
number of groups, you 
can also put several 
power supplies and 
routers in one 
distribution box. 
Connect the network cable 
(twisted pair) here. For BUS 
wiring, the connection 
between "Bridge 1-2" stays 
open, but for other wiring you 
must insert a bridge here. 
You can also lay a network 
cable to the router (if there is 
one). Connect the cable to 
connecting terminals 17 and 
18 there. An additional 
network cable goes from the 
router to the LockNodes. 
Connect the outside 
230V~ plug-in power 
supply to these 
terminals. This is 
printed on the 
connecting terminals. 
Ground the LPI-10 on 
the terminal labeled 
PE.
