Medium Voltage Controller Cable System Construction
A T T E N T I O N A T T E N T I O N Do not apply high voltage to any installed
DeviceNet cable system or its connectors. The
high voltage will destroy internal capacitors in
the connectors.
Three types of media (cable) are used in medium voltage controllers for
DeviceNet communication:
Type Flat
• Class 1, 600 volts, 8 amps
• 4 conductor – no shield or
bare wire required in Class
1 DeviceNet MV Controllers
Round
• Class 1, 600 volts, 8 amps
• 4 conductor – no shield or
bare wire required in Class 1
DeviceNet MV Controllers
Round
• Class 1, 600 volts, 8 amps
• 4 conductor – no shield or
bare wire requred in Class
1 DeviceNet MV Controllers
Use Trunk lines and drop lines Connecting units to DeviceNet
ports (unit drop lines) Trunk line for extending trunk

It is not recommended to use both Class 1- and Class
2-rated cables within the same DeviceNet system.
These two cable types are not compatible because
the following properties are different:
• Insulation class
• Overcurrent protection requirements
• Network transmission
Using Class 1- and Class 2-rated cables within the
same DeviceNet system can result in application,
code, and communication problems.
