The combination of PLZ2004WHBs and a PLZ1004WH master unit
can create an electronic load of up to 9 kW and 450 A.
The master unit displays the total current and total wattage. The
units connected in parallel can be used as a single electronic load.
• The connection of the control cables is easy. The control cable
used to connect between the master unit and the load booster and
between each load booster is one flat cable each.
• There is no power switch. The AC input power is turned ON/OFF
by the master unit.

socket in a safe place so that you can attach it to the
connector when the connector is not in use. If the
protective socket is damaged or lost, contact your
Kikusui agent or distributor.
Use the optional flat cable for the signal
wire. It comes in two lengths.

Explanation
PC01-PLZ-4W 300 mm (11.81") For connecting boosters to each other
PC02-PLZ-4W 550 mm (21.65") For connecting the master unit to a booster
CAUTION
Use a load wire with sufficient diameter for the current as well as
non-flammable or flame-resistant cover.
If the wiring that you use for the load has a high resistance, the
voltage will drop significantly when current flows, and the voltage
at the load input terminals may fall below the minimum operating
voltage. Using the following table as a reference, select wiring whose
nominal cross-sectional area is as thick as possible.
A wire's temperature is determined by the resistive loss based on
the current, the ambient temperature, and the wire's external thermal
resistance. The following table shows the current capacity of heatresistant vinyl wires that have a maximum allowable temperature of 60
ºC when one of the wires is separated and stretched out horizontally in
air in an ambient temperature of 30 ºC. The current must be reduced
under certain conditions, such as when vinyl wires that have a low heat
resistance are used, when the ambient temperature is 30 ºC or greater,
or when wires are bundled together and little heat is radiated.

PLZ2004WB/PLZ2004WHB5
Connecting the Load Wires
Consider the current that you will be using, and use wires that are
thick as possible. Also, wire them as short as possible. Use load
wires that have the same length and cross-sectional area.
The load input terminal of the master unit (PLZ1004W/PLZ1004WH) is
not designed to handle as large a current as the load input terminal
of the booster. Separate the load wires that are connected to the EUT
into those that are connected to the master unit and those that are
connected to the boosters.

CAUTION
■ Connecting load wires to the PLZ2004WHB
• To avoid damaging the product, observe the following
precautions. Be sure to use the load input terminals on the rear
panel on the master unit. Do not connect other equipment to the
load input terminal on the front panel.
The methods for connecting load wires to a booster's load input
terminal and for using the load input terminal covers and lock plates
are the same as the methods for the PLZ1004WH. For details, see the

This product falls under IEC Overvoltage Category II (energyconsuming equipment supplied from the fixed installation).
WARNING
Possible electric shock.
• This product is IEC Safety Class I equipment (equipment with
a protective conductor terminal). Be sure to earth ground the
product to prevent electric shock.
• Connect the protective conductor terminal to earth ground.
Use the supplied power cord to connect to an AC power line.
If the supplied power cord cannot be used because the rated voltage
or the plug shape is incompatible, have a qualified engineer replace
it with an appropriate power cord that is 3 m or less in length. If
obtaining an appropriate power cord is difficult, consult your Kikusui
agent or distributor.
A power cord with a plug can be used to disconnect the product
from the AC line in an emergency. Connect the plug to an easily
accessible power outlet so that the plug can be removed from the
outlet at any time. Be sure to provide adequate clearance around the
power outlet.

"Booster" to the number of booster units that
2 Set
have been connected.
3 Turn off ( ) the power to the master unit.
The menu settings are applied. This completes the settings that
are necessary to use boosters.
Performing Parallel Operation
After you finish configuring the settings on the master unit, you can
perform parallel operation. During parallel operation, the slew rate
and response speed settings on the master unit are used.
If large voltage drops occur because of increased wiring inductance
or if oscillations occur due to instability of the product caused by
current phase lag, reduce the response speed to ensure stable
operation.
Turning the Power On and Off
■ Turning the power on
Turn the master unit's POWER switch on. This will also turn the
boosters on.
Set the operation mode and configure the settings on the master unit,
and turn the load on.
■ Turning the power off
Turn the master unit's POWER switch off. This will also turn the
boosters off.
Ending Parallel Operation
To end parallel operation and return to independent operation, turn
the master unit off, and then remove the flat cables.
To return the master unit to independent operation, from the menu,
select "2. Configuration" > "1.Master/Slave" > "Booster" > "-," and then
restart the unit.
CAUTION
To avoid damaging the product, observe the following precautions.
Do not operate the PLZ-4W or PLZ-4WH alone with the flat cable
connected.

Cleaning the Dust Filter
A dust filter is installed on the inside of the louver on the front panel.
Periodically clean the filter to prevent clogging.
■ Cleaning the PLZ2004WHB's dust filter
1 Remove the lower louver from the panel.
While lifting the bottom of the removal mark with your finger tips,
slide the entire louver to the right. Then, pull it toward you.
CAUTION
• Clogged dust filters hinder the cooling of the inside of the
instrument and can cause a malfunction and shortening of the
service life.
• When the Booster is in operation, air is sucked through the dust
filter to cool the load booster. If moister is included in the dust
filter, the temperature or humidity inside the Booster increases
and may cause a malfunction.

Calibration
The booster is shipped from the factory after carrying out a strict
calibration. However, to maintain the performance, periodic
calibration is recommended.
Calibrate the master unit and the boosters as a single electronic load
in the same manner as when you calibrate the master unit alone.
For details, see "Calibration" in the PLZ1004W/PLZ1004WH User's
Manual.
For calibration, use shunt resistors and a regulated DC power supply
that match the product's current capacity.
