13. Using Modules as a Template The following procedure allows you to use the assembled modules as a template for drilling holes in the panel Due to module mounting hole tolerance it is important to follow these procedures 1 Ona clean work surface assemble no more than three modules 2 Using the assembled modules as a template carefully mark the center of all module mounting holes on the panel 3 Return the assembled modules to the clean work surface including any previously mounted modules 4 Drill and tap the mounting holes for the recommended M4 or 8 screw 5 Place the modules back on the panel and check for proper hole alignment 6 Attach the modules to the panel using the mounting screws If mounting more modules mount only the TIP last one of this group and put the others aside This reduces remounting time during drilling and tapping of the next group 7 Repeat steps 1 to 6 for any remaining modules DIN Rail Mounting The module can be mounted using the following DIN rails 35 x 7 5 mm EN 50 022 35 x 7 5 or 35 x 15 mm EN 50 022 35 x 15 Before mounting the module on a DIN rail close the DIN rail latches Press the DIN rail mounting area of the module against the DIN rail The latches will momentarily open and lock into place Installation and Wiring 3 9 Replacing a Single Module The module can be replaced while the system is mounted to a panel or DIN rail Follow these steps in order
