Harsh Enclosure Sealing
For external sealing of the harsh enclosure, refer to Figure 2-89 and follow these
steps:
1. Ensure that the appropriate approval region has been selected in setup under
Scale, Type, Approval and that the Metrology security switch S-1 is in the "on"
position.
2. Thread the end of the wire seal through the hole in the bottom edge of the
IND780 front panel, and through the hole in the center clip of the IND780 front
panel.
3. Remove the slack in the wire seal and snap the front panel down to the
enclosure so that it snaps in place in all four corners.
4. Remove any remaining slack in the wire cable.
5. Thread the end of the wire cable through the plastic seal and snap the seal
shut. Note that, to show the relationship between the components, Figure 2-89
shows the cover open, the wire slack, and the seal not yet shut.
