Attention
The IRT8I module does not receive power from the backplane. +24V
dc power must be applied to your module before operation. If power
is not applied, the module position will appear to the adapter as an
empty slot in your chassis. If the adapter does not recognize your
module after installation is completed, cycle power to the adapter.
!
Attention
Use supply wire for 10˚C above surrounding ambient.
