Mount the Controller
General Considerations
Most applications require installation in an industrial enclosure to reduce the effects of 
electrical interference and environmental exposure. Locate your controller as far as possible 
from power lines, load lines, and other sources of electrical noise such as hard-contact 
switches, relays, and ac motor drives. For more information on proper grounding guidelines, 
see the Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1
.    
Mount the controller horizontally only. Vertical mounting is not supported due to 
thermal considerations.
Be careful of metal chips when drilling mounting holes for your controller or 
other equipment within the enclosure or panel. Drilled fragments that fall into 
the controller could cause damage. Do not drill holes above a mounted controller 
if the protective debris strips have been removed.
·
Do not place the MicroLogix 1400 Programmable Controller in direct sunlight. 
Prolonged exposure to direct sunlight could degrade the LCD display.
·
The local programming terminal port is intended for temporary use only and 
must not be connected or disconnected unless the area is assured to be 
nonhazardous.
