Getting Started

Selecting the Correct Power Cord and Fuse

The standard IntelliFrame Mainframe comes with two power cords and three fuses. Before installing the mainframe, you must determine the correct fuse and power cord for your application. Use the following information to determine the appropriate power cord and line fuse for either the VX1410A or the VX1420A mainframes. This information is important to avoid overloading the power distribution system and to comply with the National Electrical Code.

For mainframe loads in the nonshaded region of Figure 1±1, use the power cord with the 15 A plug (Tektronix part number 161-0213-XX) or the power cord with the 20 A plug (Tektronix part number 161-0218-XX). For high mainframe loads combined with low input line voltages (shaded region), use only the power cord with the 20 A plug.

Select the proper fuse based on the ranges shown in Figure 1±1.
