2 3P05-PCR-LE
Handling Precautions
Handling of the U, V, and W phase Boards
• Ground yourself by touching a grounded metal object before
touching the board.
• Avoid handling the interface board in an environment subject to
strong static electricity.
• For storage, provide electrostatic protection measures such as
the anti-static bag accompanying the interface board.
• Do not drop a board or subject it to other impact.
• Do not install or uninstall the interface board with the power ON
of the PCR-LE Series.
Handling of the connecting and power-sync cable
• Do not damage the cable.
• Do not pull, bend, or apply any other stress to the cable.
Precautions When Moving the PCR-LE
Disconnect the cable(s) when moving the PCR-LE series to the
installation location or when transporting the PCR-LE. Moving a
PCR-LE series with a cable connected to the phase board may
result in breakage of the cable or connector.
Installing the board on the PCR-LE
The 3P05-PCR-LE can be installed by inserting the U, V, and W
phase boards into SLOT1 of the three PCR-LE series, respectively.
1
Check that the POWER switch of PCR-LE is off.
2
Touch a grounded metal object (for example, the
metal parts of the PCR-LE rear panel) to discharge
any static electricity from your body.
3
Remove the screws that are holding the SLOT 1
cover in place on the rear panel, and remove the
cover from the panel.
4
Hold the panel parts of the board so that the printed
circuit board side is facing up.
5
Insert the board into the slot so that the printed cir-
cuit board's connector is inserted into the connec-
tor at the back of the slot.
6
Insert the board all the way into the slot.
7
Use the screws that you removed in step 3 to fix the
board in place in the panel.
8
Follow the same procedure to install the other two
boards.
This completes installation of the phase board.
When a 3P05-PCR-LE has been inserted into the slot1 of a PCR-
LE series, that power supply can be used only in a three-phase
system. To use the power supply in a single-phase system, the
phase board must be removed from the slot1.
Connecting the bords
Use the connecting cable to connect the boards.

1
Check that the POWER switch of PCR-LE is off.
2
Place the three PCR-LE as close to each other as
possible.
Arrange them so that no stress is applied to the connect-
ing cable. A PCR-LE power supply with the U phase board
installed plays the role of the master unit that controls other
power supplies.
V
U W
For the connection as shown below, you need the optional
connecting cable (150 cm/ 280 cm). To perform parallel three-
phase operation, place the U phase to the center.
U V W
3
Connect the “TO V PHASE“ of U-phase unit and the
“FROM U PHASE“ of V-phase unit firmly with the
connecting cable using a screwdriver.
Do not remove the attached core from the cable. If you do,
reattach it (be sure to wrap the cable around the core once (2
turns)).
4
Follow the same procedure to connect the “TO W
PHASE“ of U-phase unit and the “FROM U PHASE“
of W-phase unit with the connecting cable.
Do not remove the attached core from the cable.
This completes connection of the bords.
Operation Check
Check the operation of the PCR-LE series before you perform
three-phase operation.
Check the following items with no load connected. For detail of
settings, see the PCR-LE series operation manual.
POWER switch ON
Voltage setting
OUTPUT ON/OFF
Voltage-range switching
If a trouble is occurring on even one unit, you will not be able to
perform three-phase operation.
