3-Phase Measurement (W3); Direct Connection - Fluke NORMA 4000 Operator's Manual

3-Phase Measurement (W3)

Direct Connection

Figure 5-8 illustrates a direct connection for a 3-phase measurement. Ensure that there is
no overload at the current input of the Power Analyzer. If there is a potential risk of
overload at the current input, incorporate a shunt or transducer into the circuit. If
necessary, install appropriate fuses.
To select the 3-phase (W2) method, go to General Setup and select W3. For more
information, see Chapter 7, "Configuration."
To avoid possible electric shock or personal injury:
Risk of injury when touching 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).
