System 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, as shown:
Allow at least 110 mm 
(4.33 in.) of enclosure depth to accommodate the module and the DeviceNet 
connector.
Panel Mounting
Mount the module to a panel using two screws per module. Use M4 or #8 panhead 
screws. Mounting screws are required on every module.
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.
