Mounting using the NEMA 4X panel gasket
1. Use the gasket as a template to position the
cutout. Tack or tape the gasket onto the panel
where you want to mount the unit.
2. Mark the position and dimensions of the cutout
and screw holes on the panel. Cutout dimensions
are:
! Width: 14.36 inches (364.74 mm)
! Height: 12.33 inches (313.18 mm)
Caution
To reduce the risk of fire which may result in minor
or moderate injury or cause property damage:
! Provide a minimum of 1 inch (25.4 mm) clearance
behind the ET unit for proper air circulation. In warm
working environments, this depth should be increased
to provide better air circulation.

3. Make the cutout and drill the holes.
8. Gently tighten each screw until some resistance
is encountered.
9. With a torque screwdriver, tighten the screws,
still in a circular sequence, to a torque of 12 inchpounds. This will take several passes, since each
pass reduces the previous torque setting.
4. Bring the power cable and the data cable
connections up to the cutout.
5. Place the bezel-mounted sealing gasket
(supplied) against the chassis of the ET unit so
that the gasket seals the gap between the panel
and the unit.
Depending on connector depth and cabinet
space, you may have to make your connections at
this point, before installing the unit in the cutout.
If so, skip to steps 10 and 11, then come back to
step 6.
6. Place the ET unit in the cutout. You may need
assistance at this point to hold the unit in place.
7. Attach the unit to the panel from the back using
the #10-32 screws that are supplied. Choose the
1/2" or 3/4" screws supplied, whichever is best
for the thickness of your panel.
Put a lock washer on each screw and then put a
flat washer on each screw (on top of the lock
washer).
10. Connect cables.
11. Connect the unit to power.
