Mounting the Module
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 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.
