Getting Started
Safety and Chassis Grounds
The left rear of the IntelliFrame Mainframe has a connection point for the chassis ground (see Figure 1±13).
WARNING. To avoid personal injury the safety ground screw must always be in place to ensure the proper bonding of the power supply to the mainframe. You can use the chassis ground connection to connect the grounds of one or more instruments to the mainframe. This ensures a common ground connection between instruments.
