Protective Cover Removal
and Installation
Remove the Protective Covers
1.
Read the General Safety Precautions on page
.
2.
Remove power from the drive. See Remove Power from the Drive on page
.
3.
If necessary, disconnect the DPI cable from the HIM (if present).
4.
Loosen, but do not remove, the hexalobular screws that secure the cover to
the drive chassis, slide the cover up or down, and lift the cover off the drive.
IMPORTANT
The HIM is connected via a cable to the control board and therefore the
bottom control panel cover cannot pull free from the drive until the
cable is disconnected. The cover does, however, have notches on the
side in order that it can be hung on the screws without disconnecting
the HIM cable.
