Selecting the Correct Power Cord and Fuse
The benchtop chassis comes standard with two power cords and three fuses.
Before installing the chassis 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. This information is important to avoid overloading the
power distribution system and to comply with the National Electrical Code.
For card cage loads in the nonshaded region of Figure 2–5, 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 card cage
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 2–5.
