SX5L COMMUNICATION TERMINAL USER’S MANUAL 3-3
Network Cable Wiring
Applicable Cables
Use twisted pair cable with core wires of AWG24 to AWG14 (0.2 to 2.5 mm
2
) applicable to the LONWORKS network. One
or two wires can be connected to one network interface connector. When connecting two wires together, use wires of the
same size, AWG24 to AWG16 (0.2 to 1.5 mm
2
). Whether connecting one or two wires, always use ferrules to terminate the
wires for connection to the network interface connector.
Network Interface Connector
The network interface connector features spring-clamp terminals. Push in the
orange pin to open the cable hole using a flat screwdriver, and insert a ferrule
into the cable hole. The LONWORKS network cable can be connected to the
two terminals in either polarity.
For tightening the mounting screws of the network interface connector, use a
flat screwdriver with a straight shank at the tip.
Recommended Screwdriver: Phoenix Type No. SZS 0,6 x 3,5
(Order No.: 12 05 05 3)
Tightening Torque
Tighten the network interface connector mounting screws to a torque of 0.3 to 0.5 N·m.
Applicable Ferrules
Terminators
LONWORKS networks require terminators. Connect terminators consisting of one resistor and two
capacitors shown at right (note the polarity of capacitors).
The bus topology requires two terminators at both ends of the network, and the free topology can
connect a terminator at any position in the network.

Caution
• Do not run the network cable in parallel with or in the vicinity of power, output, or motor lines.
Keep the network cable away from noise sources. Check for loose connection periodically. Loose
connection may cause overheat, resulting in possible fire hazard.
