on page 10.
2. Use the controller as a template and mark pilot holes on your
panel.
3. Drill the pilot holes for M4 or #8 screws.
4. Use M4 or #8 screws to mount the controller to your panel
with 1.16 N•m (10 lb•in) of torque.
5. Ground the module on a ground bus with a dedicated earth

ATTENTION
During mounting of all devices, be sure that all debris (such as metal
chips or wire strands) is kept from falling into the controller or I/O
modules. Debris that falls into the controller or modules could cause
damage while the controller is energized.
ATTENTION
This product is grounded through the DIN rail to chassis ground. Use zinc
plated yellow-chromate steel DIN rail to assure proper grounding. The use of
other DIN rail materials (for example, aluminum and plastic) that can corrode,
oxidize, or are poor conductors, can result in improper or intermittent
grounding. Secure DIN rail to the mounting surface approximately every
200 mm (7.87 in.) and use end anchors appropriately.
