With the ground connect mode enabled, analog output LO can float up
to ±100V above chassis ground, depending on the voltage bias source
setting. Connecting the analog outputs to external equipment that does
not allow analog output low to float up to ±100V may result in damage
to the Model 2502 voltage bias sources when the ground connect mode
is enabled.
