Guidelines for Selection of a Site and the Preparation of a Site
- Use the shortest cable runs possible that are consistent with logical equipment arrangements. Provide allowance for future additions if planned.
- Operating temperature range is
0° C to 40° C (32° F to 104° F) . Relative humidity must be less than 95% without condensation. Room Ventilation is necessary. Ensure that the environmental conditioning system can accommodate the BTU load, even during utility outages. - Ensure that the floor at the final equipment location can support the UPS weight and the weight of any material handling equipment. The UPS module can weight up to
2585 kg (5700 lb) . - Ensure that the floor along the route to the installation site can support the UPS weight and the weight of any material handling equipment.
- Place the system in a reasonably clean environment that is free of dust. The air must be free to circulate around the unit. Cooling air enters the unit through the front doors. The cooling air exhausts through the top of the enclosure. Adequate ventilation, including air conditioning, must be provided to limit heat accumulation in hot weather.
- Avoid placing the unit in direct sunlight or near other heat sources.
- Verify that the floor is a minimum of
20.7 MPa (3000 psi) concrete that can support1.44 kN (325 lb) per square foot. - The ambient temperature for the unit must be between
−20 °C to 40 °C (−4 °F to 104 °F) . There is a0° C (32° F) minimum ambient air temperature requirement for start-up of the unit. Once the UPS has been running for some time, the unit will keep warm enough in ambient temperatures as low as0° C (32° F) . However, bearing temperatures should be20° C (68° F) or higher at start-up. Preheating of the rotor will be performed by the flywheel system if necessary for colder environments. - A clearance of
914 mm (36 inch) is required from the front of the unit for service. The sides of the system can be placed against walls. If possible, leave clearance behind the unit. Clearance behind the unit will facilitate easier cable runs. The unit vents air out of the top, therefore, the ceiling height must be a minimum of2.4 m (8 ft) . Loose ceiling tiles above the unit may be moved by the airflow. - The system should not be operated in a sealed room or a sealed container. If the system must be operated in a sealed room, climate control that meets the minimum system specifications must be provided.
- If you have purchased the UPSView monitoring software, you may need to plan for the installation of a RS-232 or 485 cable. The cable must be installed from the system to the chosen local computer connection. For remote monitoring, a modem or Ethernet option and phone line or local network connection are required to interface to with UPSView.
- Plan to have appropriate communication cables installed to support the remote notification and monitoring option chosen.
- Electrical connections can enter through the top or bottom of the bypass cabinet.
The UPS must be anchored to a concrete slab that is fully cured. The slab should be poured with a minimum of 3000 psi concrete. Existing slabs should be free from cracks and seams in the vicinity of the installation. Refer to the illustrations within the section for anchoring in order to determine the requirements for the positioning of the slab.

The front of the cabinet must have at least (1) Touch screen display (2) Concrete floor (3) Anchor bolts (4) Door arc radius (5) Door arc radius (6) Door arc radius | |
The following tools and equipment are required to anchor the unit:
- Transport system (a forklift or pallet jack with a
2721 kg (6000 lb) (3 ton) capacity) - 1/2 in. drive socket wrench
- 3/4 in. socket 1/2 in. drive
- 36 in. extension bar, 1/2 in. drive
- 15/16 in. open-end wrench
- Four anchor bolts
Inspect the location for installation. Ensure that the floor meets the requirements for loading of the system. Ensure that the proper spacing for the wall and the clearance for the door is maintained.
Install the anchors in accordance with the manufacturers specifications.
The anchors must meet the following specifications:
- Anchor bolts must be 5/8 x 6 inch long (min.), Hilti Kwik Bolt II stud expansion with 4 inch minimum
- Stud expansion anchor bolts must be used in order to secure the machine properly. A stud expansion anchor bolt is recommended. There must be
101.60 mm (4 inch) of minimum embedment in the concrete. The stud expansion anchor bolts must be15.88 mm (0.625 inch) wide. The stud expansion anchor bolts must have a minimum length of152.40 mm (6 inch) . - The maximum shear load per the anchor must be
7650.9 N (1720 lb.) . - The maximum tensile load per the anchor is
3113.8 N (700 lb.) .
When the thickness of the slab or the strength of the concrete is unknown, consult "Section 1923 of the Uniform Building Code" or your Caterpillar dealer.

The flywheel is shipped with bearing retainers installed to relieve the bearing of transient forces that may be encountered during shipping and handling. The system must be anchored to the foundation prior to removing the bearing retainers. Removing the bearing retainers prior to anchoring the system will result in damage to the unit. |
Use the following procedure to anchor the system properly:
- Locate position for drilling holes.
- Drill core holes for anchor bolts.
- Lift off the system of the ground using a forklift or pallet jack.
- Remove the mounting cleats.
- Bolt the mounting cleats to the floor.
- Slide the system onto the mounting cleats.
- Bolt the system to the mounting cleats.
The unit is equipped with a zone 4 seismic qualified flywheel. Compliance with the zone 4 standard is based on calculations.
Input/Output and System Cabinet Leveling Feet Installation and Adjustment
Refer to the procedure in this section when adjusting or installing leveling feet.
Note: The leveling feet must be installed on the input/output cabinet and the system cabinet. The leveling feet must be installed after the shipping skids are removed and before the cabinets are lowered to the ground.

- Open the front doors of the cabinet to gain access to the leveling feet (four per cabinet). The leveling feet are wrapped in bubble wrap (10) and secured to the base rail of the cabinet. Refer to Illustration 2.
- Turn the locking nuts (12) clockwise until the nuts are at the bottom of the threaded shaft of the leveling foot. Refer to Illustration 3.
- Insert the forks from the forklift under the cabinet. Ensure that the forks can support the cabinet safely without tipping over. Refer to Illustration 4.
- Lift the cabinets and screw the leveling feet (13) into the base of the cabinet. Refer to Illustration 4.
- Lower the cabinet to the floor.
- Turn the leveling feet (13) until the cabinet height of
198.120 cm (78 inch) is reached. - Turn the locking nut (12) counter-clockwise to lock the leveling feet in place.
- Place the I/O and system cabinets in the appropriate position.
- Recheck the height of the cabinet to ensure that a height of
198.120 cm (78 inch) is maintained.
The installation of the cabinet leveling feet and cabinet height adjustment is complete.
