• Do not remove the printed circuit board (PCB) of the safety remote I/O module
from the case.
Doing so may cause failure.
• Carefully prevent any dust or wiring chips from entering the safety remote I/O
module.
Failure to do so may cause a fire, failure, or malfunction.
• When installing the safety remote I/O module to a control panel, provide
clearance of at least 60mm between the module's top/bottom and any other
structure or component to ensure proper airflow and to make module
replacement easy.

torque range.
Overtightening may result in damage to the screws or the module case.
