I/O Wiring—General
Input or output cables should not be run through the same multi-core cable or share the same wire.
Allow for voltage drop and noise interference with input lines used over an extended distance. Use wire
that is properly sized for the load.
Analog Outputs
Shields should be earthed, connected to the earth of the cabinet.
Do not connect unused outputs.
An output can be wired to either current or voltage.
Do not use current and voltage from the same source channel.
The outputs’ COM signals are internally shorted.

Wiring the Analog Outputs’ Power Supply
1.
Connect the "positive" cable to the "+V" 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.
