separately referenced

English Tech/Engineering Electronics / Elect Eng
"CAUTION! Do not connect any separately referenced
common wires to the SVQ-CCI-8. Failure to do so can
result in personal injury or damage to the control
or to other equipment."

...does it mean with separate earth connections?

yes, a reference voltage. Usually, this is 0 V, but it need not be that. If the reference voltage is 0, then 5 V is just that: 5 V. However, if the reference is say, 10 V, then a 10 V peak-to-peak sinusoidal signal will move between +5 and +15 V.

thanks to both of you - for jccantrell: what do you mean by "reference"? a given voltage value?

It might not be a reference GROUND connection, but it is a reference.

For example, you could bias an AC signal so that it is centered around, say, +5V DC. While this serves as the reference, it is NOT ground.

I think they mean any standard wire that has been colour coded (including the earth connection: green and yellow stripes) but is not part of the original. Is the SVQ-CCI-8 a closed entity?
