1769-L20, 1769-L30 CompactLogix™ Controllers Connect the Battery ATTENTION Do not connect or disconnect the battery unless the 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. 2.
1769-L20, 1769-L30 CompactLogix™ Controllers 9 Assemble the System The controller can be attached to an adjacent I/O module or power supply before or after mounting. For mounting instructions, see “Panel Mounting” on page 10, or “DIN Rail Mounting” on page 11. C A D B F E B 1. Disconnect line power. 2. Check that the lever of the adjacent module (A) is in the unlocked (fully right) position. 3. Use the upper and lower tongue-and-groove slots (B) to secure the modules together. 4.
1769-L20, 1769-L30 CompactLogix™ Controllers Mount the System 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 controller. Debris that falls into the controller could cause damage while the controller is energized.
1769-L20, 1769-L30 CompactLogix™ Controllers 11 Panel Mounting Procedure Using Modules as a Template The following procedure allows you to use the assembled modules as a template for drilling holes in the panel. If you have sophisticated panel mounting equipment, you can use the dimensional template provided on page 10. Due to module mounting hole tolerance, it is important to follow these procedures: 1. On a clean work surface, assemble no more than three modules. 2.
1769-L20, 1769-L30 CompactLogix™ Controllers Grounding Considerations This product is intended to be mounted to a well-grounded mounting surface such as a metal panel. Additional grounding connections from the controller’s mounting tabs or DIN rail (if used), are not required unless the mounting surface cannot be grounded. Refer to Industrial Automation Wiring and Grounding Guidelines, Allen-Bradley publication 1770-4.1, for additional information.
