B. Cut Opening and Mount NGC-UIT on Front of Panel
1. Locate the NGC-UIT on front of panel
Locate the NGC-UIT assembly on the front of the panel at a level
convenient for viewing. Make sure the cover on the back of the
assembly will not interfere with existing panel hardware.
(Refer to full size cut-out template with all dimensions
on page 7.)
Cutting Template
Note: Cutting the opening for the display is a craft sensitive
procedure; if it is not done correctly, the panel door can
be damaged. The procedure for laying out and cutting the
opening for the display must be undertaken with care, and by
personnel qualified and experienced in panel construction.
2. Prepare and mark the position of the display opening and
mounting holes
• Use the cut-out template on page 7 to lay out the opening for
the NGC-UIT display.
• Apply two layers of masking tape around the outer perimeter
of the intended opening to prevent scratching the panel
surface with the jigsaw.
• Use the template on page 7 to mark the opening and the
mounting holes for the user interface assembly.
Note: The following steps are most easily accomplished if the
panel door is on a horizontal surface.
3. Cut the display opening
Cut the opening for the NGC-UIT with a jigsaw using a 24 TPI
blade. Take care not to damage the panel door. Remove all
rough edges and burrs with a metal file before proceeding.
4. Drill the mounting holes
Drill the 10 holes with a 5 mm (3/16 inch) drill bit to mount the
NGC-UIT assembly in the panel.
5. Position the gasket on the outside of the panel door
• Place the sealing gasket between the NGC-UIT and front side
of enclosure door.

6. Mount the user interface assembly onto the panel door
• Place the NGC-UIT assembly in position; the ten mounting
screws go through the ten holes on the NGC-UIT assembly
mounting plate (see figure below).
• Place a #8 washer and #8/32 locknut on each of the ten
mounting studs; fasten only hand tight.
• Look at the front of the panel, and align the NGC-UIT
assembly so it is level (loosen nuts if necessary to reposition
the NGC-UIT assembly).
• After the display and gasket are properly positioned, tighten
the nuts to 1.13 Nm (Newton Meter) of torque using an 11/32
inch nut driver.
Do not overtighten and risk damage to hardware.
