Fig. A. Be careful not to bend it backwards. This not only marks it harder to attach the
cover but will also weaken its hold.
2. Fit the holes on the top and bottom of the terminal cover the projections on the brackets
(Fig. B) and lock in place. The figure right shows the attachment of a terminal cover to
