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 number 1769-ECR) 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 8
I/O modules may be connected to the base.
