Overview
Install your controller using these installation instructions.
!
ATTENTION
Do not remove protective debris strips until after the base and all other equipment in the panel near the base is mounted and wiring is complete. Once wiring is complete, remove protective debris strips and install processor unit. Failure to remove strips before operating can cause overheating.
!
ATTENTION
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.
!
ATTENTION
Electrostatic discharge can damage semiconductor devices inside the base unit. Do not touch the connector pins or other sensitive areas.

MISE EN GARDE
MicroLogix™ 1500 Programmable Controller Base Units 9
Publication 1764-IN001B-EN-P
Mounting the Controller
General Considerations
Most applications require installation in an industrial enclosure (Pollution Degree
2) to reduce the effects of electrical interference (Over Voltage Category II) 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.
!
ATTENTION
Vertical mounting is not recommended due to heat build-up considerations.
!
ATTENTION
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 base or processor unit could cause damage. Do not drill holes above a mounted controller if the protective debris strips have been removed or the processor has been installed.
NOTE
Remove the ESD sticker to install expansion I/O modules. An end cap terminator (catalog numbers 1769-ECR or -ECL) or an extension cable (catalog numbers 1769-CRR1, -CRR3,
-CLL1, -CLL3, -CRL1, -CRL3) must be used at the end of the group of I/O modules attached to the MicroLogix 1500 Controller. The end cap terminator is not provided with the base unit. A maximum of eight I/O modules may be connected to the base.
