Chassis Fuse Location
The power supply inlet switch is the main disconnect device and is located on the rear of
each SmartBits chassis. It houses the power switch, fuse holder, and a universal 3-wire
instrument power cord jack. The power supply connector in each SmartBits chassis has a
universal input that accepts 120/240 VAC and requires no selection or adjustment.
Warning:
To comply with safety regulations, always make sure that the chassis is pow-
ered off and disconnected when removing or inserting fuses.
Figure 1 shows the location of the power supply inlet switch on each SmartBits chassis.

Types of Power Supply Inlet Switches
There are two types of power supply inlet switches used in the SmartBits chassis. One
type is used with the SMB-10, SMB-200, SMB-2000, and SMB-600 chassis and is
described on
page 3 . The other type is used in the SMB-6000B and is described on page 4 .
The fuse holder is located within the power supply inlet switch (see Figure 2 ). Use a
small, flat-head screwdriver to open the fuse holder for each switch.
