The placement of the IRIM on the inside of any door requires that the infrared window of the IRIM 

be within a 20 degree angle of the associated Circuit Breaker Monitor infrared window line of sight.  

The shortest distance from the CBM to the IRIM (when the breaker is in the racked out position) will 

determine the most restrictive placement of the IRIM.
