Do the following cabinet procedure (see Figure 6–8).
You will need a screwdriver with a size Phillips #2
tip (Table 6–4, Items 1
and 3).
1. Make sure the front cover (optional accessory) is installed. If it is not, install
it by snapping the edges over the trim ring.
2. Locate the cabinet in Figure 6–2, page 6–12.
3. Orient the generator so the front cover is on the work surface and the bottom
side is facing you.
4. Unplug the line cord from its receptacle at the rear cover.
5. Remove the six screws at the rear of the cabinet which secure the two feet.
6. Grasp the left and right edges at the rear of the cabinet.
7. Pull upward to slide the cabinet off the generator. Take care not to bind or
snag the cabinet on the internal cabling as you remove it.
NOTE. Do not do step 8 through 13 to remove the EMI gasket(s) unless it must be
replaced due to damage. If you are not replacing the gasket, skip to step 14.
When installing EMI gaskets and/or the generator cabinet, carefully follow the
instructions given. Unless they are performed properly, the generator may not
meet its emissions requirements (EMI).
8. Locate the EMI gaskets to be removed in Figure 6–2.
9. You will need a pair of needle-nose pliers (Table 6–4, Item 6). Look for the
point where the ends of the gasket touch in the channel at the rear edge of the
cabinet.
10. Use a pair of needle-nose pliers to pry up one of the ends.
11. Grasp the EMI gasket and gently pull it out of the its channel.
12. Repeat steps 9 through 11 to remove the gasket from its channel on the front
casing.
13. To install, press each EMI gasket back into its groove at the rear edge of the
cabinet or front casing. Make sure the ends of the gasket touch, but do not
overlap, when installing. To prevent overlap, cut off any excess length.
14. To install the cabinet, do steps 3 and 4 in reverse order.
