8.2 Removing the chassis

Using a thin screwdriver, gently twist the screwdriver to pry the side tabs from the front

face. Pry just enough to release it, otherwise you’ll bend or break the tab. If you break or

bend the tab and can’t reattach the front snugly, you’ll need to reattach the front using the

4 NEMA4 screws provided. See Table 2-4 page 16.

Insert thin screwdriver under

tabs and twist slightly and

gently to disengage front
