Wiring the Test Circuit
p.25, p.37
The details of wiring the test circuits are provided in chapter 4 for the LIN1020JF and OP01-
LIN1020JF and chapter 5 for the LIN3020JF. The test circuits are grouped by the number of
AC power supplies (PCR-LEs or PCR-LE2s), and the different input power supply systems
(single-phase two-wire, single-phase three-wire, three-phase three-wire, and three-phase
four-wire) of the EUT are described. The input power supply systems of the EUT will be
denoted as 1P2W for single-phase two-wire, 1P3W for single-phase three-wire, 3P3W for
three-phase three-wire, and 3P4W for three-phase four-wire.

The wiring diagrams use schematic symbols to make the entire wiring easier to understand.
For details on how to connect the actual terminals, see the description of each part, the
appendixes, or the operation manual of the relevant product.

Parts to have ready
Please prepare your own wires and crimping terminals for connecting between the devices of
the test circuit. Select wires with sufficient withstanding voltage for the test voltage that will be
used. Using wires with a rated voltage of 600 V or higher will ensure safety up to the maxi-
mum output voltage of the AC power supplies.
We recommend that you use terminals, wires, and the like with appropriate safety (e.g. UL)
certifications.
AC power supplies that can be used
The LIN-JF can be used with PCR-LE and PCR-LE2 AC power supplies.
Because the sensing functions that are equipped in the PCR-LE and PCR-LE2 series are
used to reduce the effects of wiring impedance, conventional power supplies such as the
PCR-L and PCR-LA series or AC power supplies made by other manufacturers cannot be
used.

• The G terminal in the wiring diagrams is not the protective conductor terminal. Connecting
to the G terminal will not ground the device.
Circuit Nominal cross-sectional
area Be sure to observe the nominal
cross-sectional area.
This is especially important in
the primary current circuit to
ensure proper impedance

CAUTION
• If the sensing cables become disconnected or the polarities are incorrect, an overvolt-
age will be generated in the output of the AC power supplies. This will cause the pro-
tection function of the AC power supplies to be activated and will turn off the output.
