Considerations 
 
When installing a redundant controller pair consisting of a primary and a partner 
secondary controller: 
 
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 C300 Controller, perform the following steps. 
 
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. 
Be sure component side of IOTA is facing up. Refer to the figure below. 
 
Assemble mounting screws, washers and spacers provided.  Insert spacers 
and washers between backside of IOTA and front of channel.
