1.1 Outline of the Product
These products are Output Expansion Kits for the PCR-LA series AC power supplies. An output expansion kit enables configuration of a system capable of switching the outputs of multiple PCR-LA power supplies to obtain single- or singlephase, three-wire outputs. Output switching is performed at the Output Terminal
section. The customer should make connections between the respective units. All of
the cables required for connections are provided with the Output Expansion Kits.
A system is configured on the basis of the PCR-LA series single-phase output
power supplies. In single-phase parallel operations, two power supplies are operated
in parallel. In single-phase, three-wire operations, two power supplies generate outputs in respective phases.

1.2 Features
Single-phase/single-phase, three-wire switching system
Single-phase/single-phase, three-wire switching can be achieved without modifying cable connections. The Output Terminal has dedicated output terminals
for single-phase and single-phase, three-wire, respectively, which is convenient for connecting and disconnecting a load.
Single-phase parallel operation
Control
A system of AC power supplies capable of generating high-quality, largecapacity output can be realized. The two PCR-LA power supplies are operated
in parallel, one slave unit of which is controlled by the master unit.
■
■
■
Single-phase, three-wire operation
Control
For single-phase, three-wire outputs, two AC power supplies are assigned to
the U- and V-phases, respectively. The U-phase unit controls the V-phase unit.
Phase voltage unbalance
Generally, all phase voltages are set in one operation, but it is also possible to
set phase voltages on a phase basis.
Line voltage measurements
The system is capable of measuring not only phase voltages but also line voltages.
Single-phase, three-wire power
The power and apparent power of a load can be displayed as the total value of
those measured by the two PCR-LA power supplies. The total power factor for
the single-phase three-wire is also calculated from the total of measured values. (Note that the measurement of apparent power or the power factor
requires the RS-232C Control, the optional RC04-PCR-LA, or the optional
IB03-PCR-LA.)

2.4 Grounding
The Output Terminal can be grounded by the following two methods. One of or
both of the methods can be employed to ground the Output Terminal. However, we
recommend the method in which power connection cables are employed.
1.
Use the supplied power connection cables to connect the Output Terminal to the PCR-LA AC power supplies. This enables grounding to be
provided for the Output Terminal. For the cable connection method,
“2.5.2 Connection of Power Connection Cables”.
Connecting a power connection cable to the terminals marked “G” provides
grounding for the Output Terminal.
2.
Connect the protective conductor terminal of the Output Terminal
to an electrical ground (safety ground) directly.
WARNING
• Failure to ground the Output Terminal may cause electric shock.
• There is a possibility of physical injury or death. Be sure to provide grounding.
• Connect the ground terminal to an electrical ground (safety ground).
For grounding of the PCR-LA AC power supplies, see the PCR-LA AC Power Supply Operation Manual.
2.5 Connections for a Single-phase/ Single-phase, Three-wire Switching System
Connecting cables between the Output Terminal and the two PCR-LA AC power
supplies completes the system connections. The main cabling work consists of the
following five items:
1. PCR-LA power supplies’ input power
2. Power connection cables (to the outputs of the PCR-LA power supplies)
3. Signal connection cables
4. Parallel Operation Driver
5. Single-phase, Three-wire Output Driver
Always use the cables provided with the expansion kit.
NOTE
2-8 Installation and Preparation for Use OT01-PCR-LA/2
• The Output Terminal has no input power cables. Completing the system connections allows power to be supplied to the Output Terminal.
2.5.1 Input Power of PCR-LA Power Supplies (Two Units)
WARNING
• The PCR2000LA, PCR4000LA, and PCR6000LA are permanently
installed AC power supplies. Be sure to connect these power supplies to
the switchboard.
• There is a possibility of electric shock, which could result in injury or death.
To prevent electric shock, turn OFF the switch on the switchboard (to cut
off the power feed from the switchboard) and then connect the input power
cables.
• Connection of the input power cables to the switchboard must be carried
out by a qualified personnel.
• Install the input power cable such that the distance between the PCR-LA
power supply and the switch on the switchboard is within 3 m. This procedure facilitates operation of the switch on the switchboard in the event of
emergency.
If the distance to the switch on the switchboard is to be 3 m or more, install
the input power cables with a separate switch provided within 3 m from the
Output Terminal. For such a switch, employ one of two poles that allows
both the L and N poles to be simultaneously disconnected.
Be sure to match the polarity of the input terminals with that of the switchboard (L,
N, and (GND)), and connect the cables securely. If the polarity (L, N, and ) of
the switchboard is unknown, always have it inspected by a qualified personnel or
chief electrical technician.
If the input power cables provided cannot be used due to conditions at the installation site or for any other reason, please consult with a qualified personnel or chief
electrical technician, and select the wire size (nominal conductor cross section) of
the cable to be used in accordance with the indoor wiring regulations.
Connecting the input power cables
1. Remove the terminal-box cover from the rear of an AC power supply,
and connect the provided input power cable(s) to the INPUT terminal
board as shown in Fig. 2-6.
2.
Turn off the switch on the switchboard.
Connect the input power cable(s) to the switchboard.
3.
The switchboard ends of the input power cable(s) provided do not have terminals. For termination, attach a crimp terminal to each wire (cable) that meets
the terminal screws of the switchboard to be connected, then securely connect
the wires (cables) to the terminal screws (connection must be carried out by a
qualified personnel).
4.
Set the INPUT VOLTAGE SELECTOR to 170 V AC-250 V AC.
This system is designed especially for 200-V AC input. This step is not necessary for the PCR6000LA, as it is a power supply designed exclusively for 200V AC input.
