Control ground is isolated from power ground with the isolated analog control (option). See
Section 3.3.1
*
Signals not available with isolated analog control (option).
CAUTION!
If standard analog programming is used, note the programming return (J1-6 &
J1-24) is at the same potential as the negative output terminal of the power
supply. Observance of return connections should be made with respect to input
programming signal equipment. Improper connection may result in ground loops
and as a result internal power supply damage may occur. (Output current then
flows to chassis by means of external connection to the J1 common (J1-6 &
J1-24)).
