The weld symbol should be visible when weld fixing the GMXP0 mounting plate to
a steel surface.
Before fixing the mounting plate to the protected surface, it is important to consider cable access to
the detector. If necessary, rotate the mounting plate to the correct orientation to give cable access to
the detector. When the mounting plate is welded to the protected surface it becomes a permanent fix-
ture on that surface.
The cable access symbol indicates the direction of the cable access to the detector
when the detector is secured to the mounting plate. In the orientation shown here,
cable access to the detector is at the top of the installation.
Use two fillet welds, applied to the long side of the two cut-outs, to secure the mounting plate to the
protected surface.

Screw fixing
If weld fixing to the protected surface is not an option, the GMXP0 mounting plate can be secured by
screw fixing to a clean, paint-free area of the protected surface.
Use the weld side of the GMXP0 when screw fixing the GMXP0 mounting plate to a steel
surface.
Ensure that the correct side of the mounting plate is selected for the type of fixing to the protected sur-
face.
