Install the rail reinforcement plates and tighten using the hex nuts with captive washers, included in the kit, instead of the nuts included with the rail. Switching off the ERM circuit breaker WARNING: To prevent personal injury from electric shock or damage to the equipment, verify that the circuit breaker is in the Off position. Switching off the UPS battery circuit breaker WARNING: To prevent the UPS from dropping the load, be sure to switch off only the UPS battery circuit breaker. Installing the ERM Before installing the ERM, review and observe all warnings in "Precautions (on page 1)." WARNING: Uneven mechanical loading in the rack may cause a hazardous condition CAUTION: Always plan the rack installation so that the heaviest item is on the bottom of the rack. Install the heaviest item first, and continue to populate the rack from the bottom to the top. 1. Install the mounting rails ("Installing the mounting rails" on page 2). 2. With one person on each side of the carton, lift the chassis and lower it to the floor in front of the rack. 3. Install the mounting ears on the chassis using the screws provided. Once the battery circuit breaker is switched off, an audible alarm sounds, the Alarm LED flashes, and the LCD displays "Battery not connected."
