Patent ID: 8684476

Claim:
A method of using an angled deflection bracket in a protective cabinet for an uninterruptible power supply, comprising: providing an uninterruptible power supply having a protective cabinet housing that encloses circuitry within said uninterruptible power supply, said protective cabinet having a top wall with at least one metal knockout plate; locating an angled deflection bracket proximate an upper portion of the cabinet beneath said at least one metal knockout plate and above components of the uninterruptible power supply, said angled deflection bracket including: i) a first surface that extends to each vertical wall of the cabinet for catching falling metal debris; ii) said first surface being supported within said protective cabinet; iii) said first surface being positioned at an angle such that falling metal debris impacting the first surface slides downward along said first surface; and to enable use of said uninterruptible power supply: i) punching out said metal knockout plate to create an opening in the top wall such that metal debris falls upon said deflection bracket and slides down said first surface, thereby catching and collecting fallen debris upon said angled deflection bracket, and ii) removing said metal debris from said first surface prior to use of said uninterruptible power supply.
