Wiring the Power Supplies to both groups of Outputs
Wiring DC supply
1 First group of outputs: connect the "positive" cable to the "+V0" terminal, and the “negative” to the
"0V” terminal.
2 Second group of outputs: connect the "positive" cable to the "+V1" terminal, and the “negative” to the
"0V” terminal.
A non-isolated power supply can be used provided that a 0V signal is connected to the chassis.
Do not connect the ‘Neutral’ or ‘Line’ signal of the 110/220VAC to the device’s 0V pin.
In the event of voltage fluctuations or non-conformity to voltage power supply specifications, connect the
device to a regulated power supply.
