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.
This procedure lets you 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. On a 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.
IMPORTANT
The grounding tab, located where you install the mounting screws, enables
the module to be grounded when it is panel-mounted.
