II Safety Precautions OT01-PCR-LA/2
Safety Precautions
The following are safety precautions to be observed in order to avoid fire hazard,
electric shock, accidents, and other failures. It is not possible to predict all poten-
tial hazards; however, the following describes all known possible hazardous condi-
tions. Keep them in mind and make sure that all of them are observed properly.
Users
• This product must be used only by qualified personnel who understand the con-
tents of this operation manual.
• If it is handled by disqualified personnel, personal injury may result. Be sure to han-
dle it under supervision of qualified personnel (those who have electrical knowl-
edge.)
• This product is not designed or manufactured for general home or consumer use.
Purposes of use
• Do not use the product for purposes other than those described in the operation
manual.
Input power
• Use the product with the specified input power voltage.
• For applying power, use the power cable provided. Note that the provided power
cable is not use with some products that can switch among different input power
voltages or use 100 V and 200 V without switching between them. In such a case,
use an appropriate power cable.
Fuse
• With products with a fuse holder on the exterior surface, the fuse can be replaced
with a new one. When replacing a fuse, use the one which has appropriate shape,
ratings, and specifications.

OT01-PCR-LA/2 Safety Precautions III
Installation
• When installing products be sure to observe “Installation” described in this man-
ual.
• To avoid electrical shock, connect the protective ground terminal to electrical
ground (safety ground).
• When connecting the power cable to a switchboard, be sure work is performed by
a qualified and licensed electrician or is conducted under the direction of such a
person.
• When installing products with casters, be sure to lock the casters.
Relocation
• Turn off the power switch and then disconnect all cables when relocating the
product.
• Use two or more persons when relocating the product which weights more than
20 kg. The weight of the products can be found on the rear panel of the product
and/or in this operation manual.
• Use extra precautions such as using more people when relocating into or out of
present locations including inclines or steps. Also handle carefully when relocat-
ing tall products as they can fall over easily.
• Be sure the operation manual be included when the product is relocated.
Operation
• Check that the AC input voltage setting and the fuse rating are satisfied and that
there is no abnormality on the surface of the power cable. Be sure to unplug the
power cable or stop applying power before checking.
• If any abnormality or failure is detected in the products, stop using it immediately.
Unplug the power cable or disconnect the power cable from the switchboard. Be
careful not to allow the product to be used before it is completely repaired.
• For output wiring or load cables, use connection cables with larger current capac-
ity.
• Do not disassemble or modify the product. If it must be modified, contact Kikusui
distributor/agent.

• To maintain performance and safe operation of the product, it is recommended
that periodic maintenance, checking, cleaning, and calibration be performed.
Service
• Internal service is to be done by Kikusui service engineers. If the product must be
adjusted or repaired, contact Kikusui distributor/agent.

1-2 General OT01-PCR-LA/2
1.1 Outline of the Product
These products are Output Expansion Kits for the PCR-LA series AC power sup-
plies. An output expansion kit enables configuration of a system capable of switch-
ing the outputs of multiple PCR-LA power supplies to obtain single- or single-
phase, 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 out-
puts 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 mod-
ifying cable connections. The Output Terminal has dedicated output terminals
for single-phase and single-phase, three-wire, respectively, which is conve-
nient for connecting and disconnecting a load.
■ Single-phase parallel operation
Control
A system of AC power supplies capable of generating high-quality, large-
capacity 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 volt-
ages.
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 val-
ues. (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.)

1.4 The Applicable ROM Version of the PCR-LA
This Operation Manual applies to cases in which the expansion kit is connected to
PCR-LA AC power supplies with ROM of
version 3.35 or later.
When using above options with the PCR-LA in single-phase three-wire operation,
the PCR-LA must be required with the ROM version of 3.35 or later. If the ROM
version of the PCR-LA is 3.34 or previous version, the PCR-LA is required for the
ROM update.
To check the ROM version of the PCR-LA, refer to the operation manual of the
PCR-LA series.
In case, the PCR-LA needs the ROM update, contact your Kikusui agent or distrib-
utor.
When making an inquiry about the product, please provide us with the following
information:
• Model name of the PCR-LA power supplies
• ROM version of the PCR-LA power supplies
• Serial numbers and revision numbers of the PCR-LA power supplies (indicated
at the lower rear of the products)
• Model name of this expansion kit
• Serial number and revision number of the expansion kit (indicated at the rear of
the Output Terminal)
