6.12Input Junction Boxes and Cables

Two input power junction boxes and interconnecting cables provide under floor connection for the two input power feeds. Power terminal blocks are provided in each junction box for the connection of the input power conductors and a parity-sized ground conductor. The junction boxes are NEMA 1 enclo- sures. A main input cable assembly is provided for connection between the unit and the junction box. The cable length between the unit and junction box is 10 feet (3 meters) long.

See 5.2 - Input Junction Box Installation (Optional) on page 10 for more information and specifi- cations. See Figure 30 for wiring details.

6.13Seismic Floor Anchors

Seismic anchors are available for anchoring the unit to a concrete floor to meet seismic Zone 4 requirements. See 4.1 - Leveling and Anchoring the Unit to the Floor on page 8 for more infor- mation. Installation details are provided in Figures 11 through Figure 13 on page 25.

6.14Seismic Floor Stand

Seismic floor stands in four heights—18", 24", 30" and 36" (457mm, 610mm, 762mm and 914mm)— are available for the STS2. The stands can be fastened to the floor to meet seismic Zone 4 require- ments. See 4.0 - Locating the STS2 and Figures 33 through 44 for instructions and details for installing seismic floor stands.
