Mounting Clearance
When mounting other components in the panel and wiring cables, leave suffi-
cient clearance so that cables will not be obstructed or damaged. In addition,
absolutely do not cover the slits on the PT.

Securely tighten the screws to a torque of 0.1 to 0.25 N·m for the NV3W/
NV3Q and 0.2 to 0.3 N·m for the NV3W-V1 or NV4W. Be sure to tighten the
screws correctly.
If the screws are tightened too much, the panel may warp, the touch switches
may not operate, and waterproof performance may decrease.
The mounting screws for the NV3W-V1/NV4W are not commercially available.
The waterproofing performance may decrease or other problems occur if
screws other than the special mounting screws are used.
When applying for UL certification for devices connected to the NV-series PT,
observe the following precautions.
• When the PT is installed in equipment, it must conform to standards by
being included as part of the equipment enclosure.
• The rear panel of the NV-series PT is not certified as an enclosure, so
provide a fireproof enclosure (i.e., a metal barrier) so that the rear panel
and sides of the PT are covered.
