Mounting Expansion I/O
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 communication bus.
ATTENTION: During panel or DIN rail mounting of all devices, be sure that all
