Precautions for Safe Use
• When operating on the operation panel, make sure to keep metal particles from entering the
Unit.
The mounting panel must be between 1.6 and 4.8 mm thick. The NB Unit must be installed
in a control panel.
For the sake of waterproof and dustproof, all the fixators must be evenly tightened to a
torque of 0.5~0.6 Nm. If the tightening torque exceeds the specified value, or the tightening
is not even, deformation of the front panel may occur.
Make sure that the operation panel is clean, unbent, and strong enough for the installation
process.
