lThe door switch with the longer wires is installed on the
left side of the enclosure.
3. Open both doors on the enclosure.
4. Remove three 10-32 × 3/8-inch flat-head Phillips screws and
three 10-32 nuts that secure the two top door hinges to the

pre-drilled, go to Step 2.
2. Mark the locations for the two safety screws on the left side
of the enclosure as follows:
lEach screw must be 1/2-inch below the top of the
enclosure panel.
lAllow approximately 9.4 inches between the safety
screws.
Figure 2-4: Example of the locations to drill holes for the
safety screws.
3. Use a 1/4-inch drill bit to drill two holes in the locations that
you marked in Step 2.
4. Insert one safety screw into each hole.
5. Use the Torx L-key and a 5/16-inch wrench to secure a lock
nut to each safety screw.
