Use the DS1000 System Load Factor Calculations chart to verify your system's configuration. To check your system configuration: 1. Indicate the quantity for each item installed in the Qty column. 2. For each item, multiply the Qty times the Load Factor and enter the value in Total Load. 3. Add all the values in the Total Load column and enter the value in Item 1. 4. Compare the entry in Item 2 to your entry in Item 1. Item 1 must always be equal to or less than the entry in Item 2. Do not operate your system if the System Load Factor total (Item 1) exceeds the allowable load of 30 (Item 2).
