The Dual Pressure Switch Module can be mounted in several different ways using the M4 SS threaded inserts located on the back of the box (see
Figure 10 below). The module can be mounted threading directly to the inserts, attaching flanges to allow for the use of self-tapping screws, or by
attaching magnets to the box to secure the module in its mounting location. Tighten screws to hand tight to avoid stripping the threaded inserts away
from the box. Thread locker should be used in higher vibration environments.
If mounted in a vertical orientation, remove the nameplate from the module and apply the supplied nameplate so that the content is readable.
Figure 10 – Threaded Insert

DIOM 800095-A 9 7/22/2022
CAUTION
Overtightening the screws threaded into the threaded inserts can result in stripping the threaded inserts away from the box.
The use of stainless-steel screws can result in seizing of screw in the threaded insert. Leading to overtightening.
3.5.1 Direct Mounting
Holes will need to be predrilled at the mounting location to allow for screws to be threaded in from behind. Figure 10 below gives the hole location
dimensions of the threaded inserts. Appendix A also contains a printable drill guide to aid in the mounting process. Do not use stainless-steel
screws. Seizing of the screw inside the threaded insert can occur, resulting in overtightening, and the potential stripping of the threaded inserts away
from the box
Figure 11 – Threaded Insert Dimensions
3.5.2 Flange Mounting Kit
Option to attach flanges to the box to allow r the use of self-tapping screws. The flanges are secured to the module using the supplied hardware. Adjust
