Safety SAVE THESE INSTRUCTIONS General safety WARNING! All electrical power and control wiring must be installed by a qualified electrician and comply with local and national codes. WARNING! When connected, the UPS contains energy from both AC and DC sources. If the UPS has dual mains supply, be aware of the two AC supply sources. Risk of electric shock - parts inside the UPS are energized from the battery supply even the AC power is disconnected. WARNING! Servicing of batteries should be performed or supervised by personnel knowledgeable of batteries and the required precautions. Keep unauthorized personnel away from batteries. WARNING! Batteries do not contain serviceable parts. Only APC authorized personnel may open batteries. WARNING! Do not dispose of battery or batteries in a fire. The battery may explode. Do not open or mutilate the battery or batteries. Released electrolyte is harmful to the skin and eyes. It may be toxic. WARNING! Risk of Energy Hazard, 96 V, 7.2 Ampere-hour battery. Before replacing batteries, remove watches, rings, or other metal objects. High energy through conductive materials could cause severe burns. WARNING! When handling batteries, wear rubber gloves and boots. Do not lay tools or metal objects on top of batteries. WARNING! When replacing a Battery Unit, replace with the same number of the APC SYBT1 (always replace a whole Battery Module (4 Battery Units) at a time). WARNING! Only trained personnel familiar with the construction and operation of the equipment and the electrical and mechanical hazards involved, may install and remove system components. For configurations including customer-supplied external batteries, refer to manufacturer s battery installation and maintenance instructions. 2 AIS 3100 20 and 40 kva, 400 V, Site Preparation and Installation Manual 990-2387

Output Pwr Zone Reset Probe 10/100Base-T 10/100 AP9619 Network Management Card EM Mechanical Assembly Stabilizing Brackets Always install the Stabilizing Brackets on the 352 mm Enclosure (shipped with the UPS) to enhance the stability of the Enclosure. Note Attach the Stabilizing Bracket to the UPS Enclosure re-using the screws used to secure the UPS to the pallet during shipment. Stabilizing Bracket If the Enclosure needs to be moved after Stabilizing Brackets have been attached to the Enclosure, the Stabilizing Brackets must be pushed up into their high position. Loosen the two screws of both Stabilizing Brackets, and push the bracket up into the high position. When the Enclosure has reached its new position, push the Bracket into its down position again, and tighten the screws. WARNING! For stability reasons, do not remove Stabilizing Brackets from 352 mm Enclosures. 990-2387 AIS 3100 20 and 40 kva, 400 V, Site Preparation and Installation Manual 15

Leveling Feet Note Verify that the installation has been electrically wired before setting the leveling feet. Setting the leveling feet Set the leveling feet to ensure the Enclosure is horizontal when it is in its final operating position. Use a 13/14-mm wrench (shipped with the Enclosure) to adjust all 4 leveling feet from front to back, and left to right, until the pads make solid contact with the floor. Use a level tube to check the Enclosure is horizontal. 13/14-mm wrench CAUTION! To avoid equipment damage, do not move the Enclosure after the leveling feet have been lowered. 16 AIS 3100 20 and 40 kva, 400 V, Site Preparation and Installation Manual 990-2387

Floor Anchoring Drilling floor holes for floor anchoring Note If your UPS installation requires floor anchoring, the UPS installation must be anchored to the floor, re-using the brackets that secured the Enclosure to the pallets when shipped.
