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
(metal chips, wire strands, etc.) is kept from falling into the module. Debris
that falls into the module could cause damage on power up.
