Before You Begin
Use this document as a guide for installing and powering-up your 1769-L20, -L30 CompactLogix controller system. You should already be familiar with the CompactLogix system components.
You must FLASH upgrade the firmware on your CompactLogix controller before you can use it. The controller ships with firmware revision 1.x but must be upgraded to match the version of RSLogix 5000 that you are using (e.g. if you are using RSLogix 5000 V11, you must upgrade your CompactLogix controller firmware to revision 11.x before using it. For more information on upgrading your controller’s firmware, see page 17.

System Planning
Consider the following when planning your CompactLogix system:
The CompactLogix controller is always the left-most module in the system.
The controller must be located within four modules of the system power supply. Some I/O module’s may be located up to 8 modules away from the power supply. See the documentation for your 1769 I/O modules for details.
The 1769-L20 controller supports up to 8 I/O modules in a maximum of 2 I/O banks (1 expansion cable allowed).
The 1769-L30 controller supports up to 16 I/O modules in a maximum of 3 I/O banks (2 expansion cables allowed).
Each I/O bank requires its own power supply.
Only one controller can be used in a CompactLogix system.
A 1769-ECR (right end cap) or 1769-ECL (left end cap) is required to terminate the end of the communication bus.

Install the Controller
The 1769-L20 and 1769-L30 controllers are suitable for use in an industrial environment when installed in accordance with these instructions. Specifically, this equipment is intended for use in clean, dry environments (Pollution Degree 2(1)) and with circuits not exceeding Over Voltage Category II(2) (IEC 60664-1).(3)
Prevent Electrostatic Discharge
ATTENTION
!
Electrostatic discharge can damage integrated circuits or semiconductors if you touch bus connector pins. Follow these guidelines when you handle the module:
Touch a grounded object to discharge static potential.
Wear an approved wrist-strap grounding device.
Do not touch the bus connector or connector pins.
Do not touch circuit components inside the module.
If available, use a static-safe work station.
When not in use, keep the module in its static-shield bag.
Remove Power
ATTENTION |
Remove power before removing or inserting this module. |
|
When you remove or insert a module with power applied, an |
||
|
!injury or property damage by:
sending an erroneous signal to your system’s field devices, causing unintended machine motion
causing an explosion in a hazardous environmentelectrical arc may occur. An electrical arc can cause personal
Electrical arcing causes excessive wear to contacts on both the module and its mating connector. Worn contacts may create electrical resistance.
(1)Pollution Degree 2 is an environment where, normally, only non-conductive pollution occurs except that occasionally a temporary conductivity caused by condensation shall be expected.
(2)Over Voltage Category II is the load level section of the electrical distribution system. At this level transient voltages are controlled and do not exceed the impulse voltage capability of the product’s insulation.
(3)Pollution Degree 2 and Over Voltage Category II are International Electrotechnical Commission (IEC) designations.

|
environment is known to be non-hazardous. |
||
|
!
The controller is shipped with the battery packed separately. To connect the battery, follow the procedure shown below.
1. Slide the battery door (a) forward.
|
IMPORTANT |
Do not remove the plastic insulation covering the battery. The |
|
insulation is necessary to protect the battery contacts. |
|
|
|
