Measurement with Shunt
Figure 5-9 illustrates the connections for a 3-phase measurement using a shunt. The
connecting leads to the shunts should be as short as possible in order to prevent noise
voltages.
XW Warning
To avoid possible electric shock or personal injury:
• Do not touch sense terminals. The sense terminals at the
shunts are powered with the same voltage as the power
connections.
• Shunts are not isolated. Never touch the sense terminals at
the shunts.
• Do not touch connections, internal circuits, and measuring
devices that are not connected to earth ground.
• Always adhere to the instructions regarding the sequence of
connection (see Chapter 5, “Connecting Sequence”).
