Precautions
WARNING: There is a risk of electric shock from high earth conductor leakage current when connecting multiple pieces of Information Technology Equipment to Compaq 3000 Series Uninterruptible Power Systems (UPS):
The summation of the input power for multiple pieces of Information Technology Equipment through the use of a UPS can result in high earth conductor leakage current. For UPS products that have detachable AC power cords, the total combined earth conductor leakage current should not exceed 3.5 mA.
WARNING: There is a risk of personal injury from the hazardous energy levels associated with UPS batteries. The maintenance and replacement of batteries must be carried out by qualified service personnel.
WARNING: The 3000 Series UPS models weigh 132 lb (60 kg) when fully assembled. To reduce the risk of personal injury or damage to the equipment:
■Observe local occupational health and safety requirements and guidelines for manual material handling.
■Obtain adequate assistance to lift and stabilize the chassis during installation or removal.
■Remove the battery pack to reduce the overall weight of the product by approximately 60 lb (27 kg).
■Adhere to the precautions and guidelines set forth in the “Rack Stability” section to follow.
