1769-L32C, 1769-L35CR CompactLogix Controller 8. Move the end cap terminator back along the tongue-and-groove slots until the bus connectors line up with each other. 9. Lock the end cap bus terminator.
1769-L32C, 1769-L35CR CompactLogix Controller 19 Mount the System ATTENTION ATTENTION IMPORTANT During panel or DIN rail mounting of all devices, be sure that all debris (such as metal chips or wire strands) is kept from falling into the controller. Debris that falls into the controller could cause damage while the controller is energized. When attaching the controller, power supply, and I/O modules, make sure the bus connectors are securely locked together to be sure of proper electrical connection.
1769-L32C, 1769-L35CR CompactLogix Controller Panel Mounting Mount the controller to a panel by using two screws per module. Use M4 or #8 panhead screws. Mounting screws are required on every module. IMPORTANT The grounding tab, located where you install the mounting screws, enables the module to be grounded when it is panel-mounted. This procedure lets you use the assembled modules as a template for drilling holes in the panel.
1769-L32C, 1769-L35CR CompactLogix Controller 21 6. Attach the modules to the panel by using the mounting screws. IMPORTANT If mounting more modules, mount only the last one of this group and put the others aside. This reduces remounting time when you are drilling and tapping the next group of modules. 7. Repeat steps 1…6 for any remaining modules. DIN-rail Mounting The controller can be mounted by using the following DIN rails: • EN 50 022 - 35 x 7.5 mm (1.38 x 0.30 in.) • EN 50 022 - 35 x 15 mm (1.
