Improper repairs can create a safety hazard. ! For floor-standing products, install and extend bottom stabilizers before installing options and boards. ! Verify that the AC power supply branch circuit that provides power to the rack is not overloaded. This will reduce the risk of personal injury, fire, or damage to the equipment. The total rack load should not exceed 80 percent of the branch circuit rating. Consult the electrical authority having jurisdiction over your facility wiringand installation requirements.
