ATTENTION: When attaching I/O modules, it is very important 
that the bus connectors are securely locked together to ensure 
proper electrical connection.
IMPORTANT
A 1769-ECR or 1769-ECL right or left end cap must be used to 
terminate the end of the serial communication bus.
ATTENTION: During panel or DIN rail mounting of all devices, be 
sure that all debris, such as metal chips and wire strands, is kept 
from falling into the module. Debris that falls into the module 
could cause damage on power up.
