3. Installing the PT
• Installing the NV3W
Used the enclosed mounting brackets (4) and mounting screws (4) to
secure the PT to the mounting panel.
• Installing the NV3W-V1/NV4W
Secure the PT to the panel using the mounting brackets (4) and mounting
screws (4) that came with the PT.
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.
• Installing the NV3Q
Used the enclosed mounting brackets (2) and mounting screws (4) to
secure the PT to the mounting panel.

(1) The PT must be installed in a control panel.
(2) When preparing the panel, do not let metal debris enter the PT.
(3) The panel on which the PT is installed must have a thickness of 1.6 to
4.8 mm. To maintain waterproof and dust proof performance, the mount-
ing bracket screws must be tightened evenly to an appropriate torque.
If the bracket is tightened beyond the specified torque, or if the tightening
is not applied evenly, it may cause warping of the front sheet.
The panel must also be free of dirt and warping, and must be sufficiently
strong enough to support the PT.
(4) Always replace the Waterproof Packing when remounting the PT.
