4.1.2. SPLIT-PHASE, 3-WIRE (SPLIT-PHASE FROM A CENTRE-TAP TRANSFORMER): 3P-3WD2
Connect the N terminal to the neutral.
Connect the VE/GND terminal to the earth (optional on this
type of network).
Connect the V1 terminal to the L1 phase.
Connect the V2 terminal to the L2 phase.
Connect the IN current sensor to the neutral (optional on this
type of network).
Connect the I1 current sensor to the L1 phase.
Connect the I2 current sensor to the L2 phase.
Always check that the arrow of the current sensor
points towards the load. This ensures that the phase
angle will be correct for power measurements and
other measurements that depend on the phase.

Source Load
Always check that the arrow of the current sensor points towards the load. This ensures that the phase angle will be correct for
power measurements and other measurements that depend on the phase.
However, when a recording session has ended and been uploaded to a PC, it is possible to change the direction of the current (I1,
I2, or I3) using the PEL Transfer software. This makes it possible to correct the power calculations.
The crocodile clips can be screwed onto the voltage leads, keeping the assembly tight.
Only the AmpFlex® A196A sensors delivered with the instrument are tight.
