Connecting the Power Supply Enclosure to the Network 
The power supply provides electrical power to make the system work. Some network layouts 
require more than one power supply.  

Location is also an important consideration when locating power supply enclosures on your 
network. Contact the factory for determining how many power supply enclosures your system 
needs, as well as where they need to be installed. 

After you’ve mounted the power supply enclosure(s), you can connect them to your network. 
To connect a power supply to the network: 

1.  Attach a KwikLink connector included in the bag with power cables to the flat 

cables. One connector is used for the network grey cable and one connector is used 
for the auxiliary power black cable. 

2.  Align the square connector of the grey drop cable so the cable leads down from the 

connector. Evenly press the square connector onto the top of the bottom KwikLink 
connector. It should make two audible snaps when properly seated. 

3.  Align the square connector of the black drop cable so the cable leads down from the 

connector. Evenly press the square connector onto the top of the upper KwikLink 
connector. It should make two separate, audible snaps when properly seated. 

4.  Attach the keyed round connectors to the receptacles on the side of the power supply 

enclosure marked 24 VDC POWER SUPPLY. Tighten the cord grip ring until 
snug. 

5.  Dress the excess cables with cable ties so they do not interfere with operation and to 

give a pleasing appearance. 

If more than one power supply is required to properly energize the grey network flat cable: 

1.  Remove the terminal block jumpers on all but the most centrally-located network 

power supply enclosures. 

For locations of jumpers, refer to the drawing shipped inside the power supply 
enclosure
