Mounting pattern 1 is the easiest to achieve, as it does not require a

panel punch. For additional mounting assurance, Mounting Pattern

2 also uses the flats on the mounting shaft to prevent rotation.

Installation

This product requires the use of the bezel. It supports the knob

and guides it during operation to assure long life and smooth

operation.

1. Open the attached hardware bag and check contents versus

the list on the next page.

2. Put one of the 3/4" hex nuts on the neck and then the 3/4"

lock washer. Make sure to run it down far enough to leave

space the get the neck through the panel.

3. Bring the switch in through the back of the panel making sure

to align the anti-rotation stud.

4. Adjust the mounting nut behind the panel until ½ - ¾" of the

threaded portion of the neck (not including the shaft) extends

through the panel.

5. Holding the switch in place, place the bezel over the neck and

align it to the anti-rotation pin.

6. Put the second mounting nut on the threaded neck and

tighten to 216 in-lbs maximum.

7. Line up the knob with the flat on the shaft, and press it in

place until it bottoms out.

8. Check to make sure that the lockout opening on the bezel and

the lockout opening on the knob line up so that a padlock

shackle can be placed through both in the off position. If this

is out of alignment, remove the knob and adjust the two

mounting nuts until you can align the bezel and knob.

9. Once satisfied with the fit of the knob use the 4-40 pan head

screw ( 2 in-lbs torque) to lock the handle in place. Then press

the plug into the hole with your fingers.

10. Remove the nuts and lock washers from the two 3/8" studs.

Make good contact!

Unlike many other Master Disconnects on the market,

the 75920 studs are permanently affixed to the base,

so you can remove all the hardware and use the entire stud.
