External Sealing of the Harsh Enclosure

For external sealing of the harsh enclosure, refer to Figure 2-56 and Figure 2-59
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 SW1-1 is in the
"on" position.
2. With the front panel installed on the enclosure and snapped into place, thread
the free end of the wire seal through either the left or right hole in the IND560
front panel, and through the hole in the retaining clip.
3. Thread the end of the wire cable through the hole in the plastic seal (as shown
in Figure 2-59), remove any remaining slack in the wire, and snap the seal
shut.
