2.2.5 Connecting the System Ground

CAUTION

Separate the frame ground from the signal ground at the user

system. When the frame ground is connected to the signal ground

and the emulator is then connected to the user system, the emulator

will malfunction.

The emulator's signal ground is connected to the user system's signal ground via the evaluation chip board. In the

E6000H station, the signal ground and frame ground are connected (figure 2.5). At the user system, connect the

frame ground only; do not connect the signal ground to the frame ground.

If it is difficult to separate the frame ground from the signal ground in the user system, ground the frame to the

same outlet as the 100-V to 240-V power supply of the emulator station (figure 2.6) so that the ground potentials

become even.

WARNING

Always switch OFF the emulator and user system before

connecting or disconnecting any CABLES. Failure to do so will

result in a FIRE HAZARD and will damage the user system and the

emulator or will result in PERSONAL INJURY. The USER PROGRAM

will be LOST.

The user system must be connected to an appropriate ground so as to minimize noise and the adverse effects of

ground loops. When connecting the evaluation chip board and the user system, confirm that the ground pins of

the evaluation chip board are firmly connected to the user system's ground.
