Panel cutout dimensions to install a display are shown in Appendix D.
Overall dimensions, optional flush mount dimensions and enclosure
dimensions are also shown in Appendix D.
Use these steps to mount a DL20 in a custom panel, enclosure, or optional
Bulletin 2706 enclosures (Cat. No. 2706-NE1 and 2706-NE2). When
properly installed, the display faceplate provides a NEMA Type
12/13 enclosure.
Mounting Procedure
1. Cut and drill the appropriate mounting holes according to the panel cutout
dimensions found in Appendix D.
ATTENTION: Displays should not be installed in a panel until
all panel cutouts and holes are completed. Metal filings created
!
when cutting and drilling could enter ventilation holes on the
display and cause the display to fail.
Mounting hardware (nuts) behind the panel can be eliminated by drilling and
tapping the six mounting holes in the panel. Number 10 mounting screws are
recommended.
2. Insert the display in the panel cutout and tighten the six faceplate
mounting screws.
