Mounting
Minimum Spacing
Maintain spacing from enclosure walls, wireways, adjacent equipment, etc.
Allow 50 mm (2 in.) of space on all sides for adequate ventilation.
Figure 2.2 Space Requirements
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 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 at power up.
