Following are the parts included: 
 
a C300 Controller assembly (controller module with IOTA board and mounting 
hardware) 
 
STP Cat5 Redundancy Cable (Orange cable) 
 
2 STP Cat5 Ethernet cables (one Yellow cable, one Green cable) 
 
2 or 4 IOLink cable assemblies for connecting on-board IO Link interface if the 
controller is supporting Series 8 I/O modules. 
 
Ensure the cabinet enclosure is connected to a protective earth ground using #8 AWG 
solid copper wire. There should be metal to metal contact between the grounding bus 
bar and the enclosure as well as the channel. 
 
Considerations 
 
The secondary controller should be installed in the same cabinet as the primary 
controller. 
 
The secondary controller may be installed on a separate channel from the primary 
controller. 
To install a partner secondary C300 Controller, perform the following steps. 
 
If the primary C300 FB already exists in Control Builder and it is currently 
configured as a redundant controller, select the Redundancy tab and click the 
Disable Synchronization button to set the Auto-Synchronization State 
parameter to "DISABLED." 
Refer to appropriate site location drawings for the specified controller 
installation location, controller Device Index (FTE address) and wiring 
diagrams. 
Identify the mounting location on channel and align mounting holes in IOTA 
with screw hole locations on the channel.
