DANGER
hazard of electric shock, explosion, or arc flash
Cover the front of the UPS with a plastic sheet while making anchoring holes to prevent dust or other conductive particles from entering the cabinet.
Failure to follow these instructions will result in death or serious injury.
WARNING
hazard of tilting
All rear and front seismic anchoring brackets must be installed.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
  1. Cover the front of the UPS with a plastic sheet (marked (A) in the illustration) to protect against dust from drilling in the floor. Fasten the plastic sheet to the UPS with tape or similar to create a seal. The packaging bag can be cut and reused for the plastic sheet.
