Wiring the Output’s Power Supply

Outputs

Wiring DC supply

Connect the "positive" cable to the "+V0"
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.
