Closing the Housing
To close the housing:
1. Verify that the cover gasket is in the groove around the perimeter of the rear cover.
2. If the front of the unit was removed, lift the front of the DS100 to allow the hinge pin
to be installed, align the front unit with the rear cover, and attach the hinge pin with
the retaining clip.
3. Turn on the power to verify that the lights on the boards are functioning. See “Table
4 Visual Indications” on page 11. If the environment does not allow powering,
proceed to the next step.
4. Verify all connectors are seated. Verify wires are not strained and are not impeding
the ability to close the unit.
5. Lift the front of the unit and seat the front cover against the rear enclosure.
6. Tighten the cover screws hand tight, and then torque them in alternate pattern to
60 in-lb +/- 10 in-lb.
