Tip
If installing the MEB at installation location #3 shown in Figure

access the mounting studs.

1. Ensure power is off and the area is non-hazardous.
2. Open the enclosure door. Referencing Figure 4–2, locate the mounting
studs you will be using for this MEB.
3. If you are mounting the MEB onto an MEB that is already installed, go
to step 6. If not, install a star lock washer and 3/8-inch standoff onto
each mounting stud. See “A” in Figure 4–3.
4. Install the MEB onto the standoffs.
5. Install a star lock washer and 3/4-inch standoff to secure the MEB. See
“B” in Figure 4–3.
6. If you are mounting the MEB onto an MEB that is already installed,
place the MEB over the standoffs, and then secure it with a star lock
washer and 1/4-inch standoff. See “C” in Figure 4–3.
7. Referencing the appropriate section of this chapter, wire the MEB as
required.
