Earth Ground Connections
Your connection to Earth Ground is important to the safety of your equipment, your
personnel, and the integrity of your measurement.
The unit housing is plastic and does
not require an earth ground connection to itself.
But if mounted in a metal housing, an
earth ground wire connection to that
housing’s ground terminal (green screw) is usually
required using suitable wire per applicable codes. Isolated circuits wired to this splitter
are each normally earth grounded. Power connections usually earth ground at DC-.
Output connections apply earth ground at the output common terminal and circuits wired
to analog inputs should be earth grounded as reflected in their connection diagrams for
the specific plug-in module model. Ground connections noted are recommended for best
results and help protect the unit and its isolated circuits by giving each isolated circuit a
low impedance path to steer potentially destructive transient energy away from sensitive
circuitry, where it can be dissipated safely. Refer to the Electrical Connection Drawings for
recommended input, splitter output(s), and power ground connections.
Split Output Connections (Each Splitter Output Supports Voltage or Current)
This carrier includes both a voltage output and current output terminal at each of two
isolated output channels at TB3 and TB4 and these outputs share a common connection in
the channel. Choose which output signal you need for your application and load only the
output of interest (do not load both outputs of a channel simultaneously). A connection
to earth ground connection is normally made at the common terminal of each isolated
output as shown below.
