4.5 MECHANICAL INSTALLATION, All Models

The following subsections describe rotating the enclosure housing relative to the measuring cell to clear
obstructions or view the optional display, orienting the display for ease of reading, and installing
electrical conduit and cables.

4.5.1 Enclosure Rotation

1. Loosen the enclosure setscrew using a 3/32" Allen wrench. See Figure 4-14. The enclosure can be
rotated approximately 135º in either direction from the point where the enclosure rotation arrow
points directly at the enclosure setscrew; see Figure 4-14.
If the high end of the ramp-shaped recess in the enclosure neck is rotated past the
enclosure rotation arrow on the measuring cell, damage to internal electrical
connections can occur, requiring replacement of the measuring cell.
After positioning the enclosure, tighten the enclosure setscrew to between 30.1 in-lbs and 31.9 in-lbs
(3.4 N-m and 3.6 N-m).
2. Position the display as necessary. Refer to Section 4.5.2.
