Chapter 2 Configuring and Installing the SCXI Chassis

Selecting Voltage and Replacing the Fuse for the SCXI-1000
and SCXI-1001
If you ordered the chassis with the appropriate part number (the -0x
extension of the kit part number corresponds to your geographical region),
the voltage tumbler and fuse are correct for operation in your geographical
region. Check the voltage on the voltage tumbler to ensure that you have
the correct voltage tumbler setting and fuse.
The SCXI chassis can operate with line voltages of 100, 120, 220, and
240 VAC. The voltage tumbler in the power entry module determines the
voltage for which the chassis is configured. You can identify the operating
voltage by looking at the number on the power entry module when the door
that covers the tumbler is closed. The fuse is 5 × 20 mm, which has a
current rating relative to the operating voltage. Table 2-4 shows the proper
voltage selections and fuse ratings for different regions.
Caution For continued protection, replace fuses only with fuses of the same type and
rating.
