Turning the power off
1
Press the ( ) side of the POWER switch to turn
the power off.
CAUTION
After you turn the POWER switch off, wait at least 5 seconds
after the fan stops before you turn the POWER switch back
on. Repeatedly turning the POWER switch on and off at short
intervals will shorten the service life of the POWER switch and
the internal input fuse.
Selecting the load cables
WARNING
• Risk of re. Use load cables whose capacity is adequate
for the PLZ-5W’s rated output current.
• Risk of electric shock. Use load cables with a voltage
rating that meets or exceeds the isolation voltage
(±500 V) of the PLZ-5W’s load input terminals.
CAUTION
Use load cables with a core diameter that is appropriate for the
amount of current being used and with sturdy, ame-resistant
insulation.
If the wiring that you use for the load has a high resistance,
the voltage will drop signicantly when current ows, and the
voltage at the load input terminals may fall below the minimum
operating voltage of the PLZ-5W. Using the following table as a
reference, select wiring whose nominal cross-sectional area is
as thick as possible.

WARNING
Risk of electric shock.
• Do not touch load input terminals when the output is
turned on.
• The load input terminals on the front panel are con-
nected internally to the load input terminals on the rear
panel. The voltage applied to the terminal on one side is
transmitted directly to the terminal on the other side.
• Be sure to use the load input terminal cover.
CAUTION
To avoid damaging the product, observe the following precau-
tions.
• Do not connect the DUT to the load input terminals while the
PLZ-5W’s load is turned on.
• Do not connect electronic loads to the load input terminals on
the front panel and those on the rear panel at the same time.
• Do not invert the polarity when connecting. An overcurrent
might ow when the load is turned on.
To avoid overheating, observe the following precaution.
• Attach crimping terminals to the cables, and use the supplied
screws to connect the cables.

■Attaching the load input terminal cover
You can adjust the diameter of the holes that the load cables
pass through by changing the positions in which the top and
bottom load input terminal covers are put together. There are
two available positions. Use the appropriate position for the load
cables that you are using.
• For cables up to ø10 mm: Put the top and bottom load input
terminal covers together so that the hole diameter is small.
• For cables that are between ø10 and 20 mm: Put the top and
bottom load input terminal covers together so that the hole
diameter is large.

Connecting to the Device Under
Test (Cont 'd)
Connecting to the load input terminals on the
front panel
The load input terminals on the front panel enable you to
easily connect the device under test (DUT) to the PLZ-5W. The
specications of the PLZ-5W are for the load input terminals on
the rear panel and the load input terminals on the front panel
may not meet the specications.
WARNING
• Risk of electric shock. Attach insulation caps to the
crimping terminals.
• The rated current value of the load input terminals on
the front panel of the PLZ1205W is 80 A. When a current
of 80 A or more ows to the load input terminals on the
front panel, an alarm occurs and load off.
1
Turn the POWER switch off ( ).
2
Make sure that the output of the DUT is off.
3
Remove the protection plate of the load input
terminals on the front panel.
Keep the removed protection plate and screws in a safe
place. By attaching the protection plate when not using the
load input terminals on the front panel, the PLZ-5W can be
used in a safe and compact manner.

the front panel to the positive (+) polarity of the DUT, and the
negative (−) polarity of the load input terminal on the front
panel to the negative (−) polarity of the DUT.
Connecting the Sensing Cables
To perform remote sensing, connect the sensing cables.
A voltage measurement point can be changed from a load input
terminal to an arbitrary sensing point by executing remote sens-
ing. By setting sensing points to a DUT end, inuences such as
voltage drops caused by the resistance of the load cables can
be reduced and the load current can be stabilized.
CAUTION
• Risk of damage to the internal circuitry. Never wire the sensing
terminals while the POWER switch is turned on.
• If the remote sensing cables come loose while remote sensing
is in use, the PLZ-5W and DUT may be damaged. Be sure to
connect the cables securely.
Unlike the load cables, there is no need to consider the cur-
rent capacity for the sensing cables. However, for adequate
mechanical strength, use wires whose nominal cross-sectional
area is 0.5 mm2 or greater.
1
Turn the POWER switch off ( ).
2
Remove the sensing terminal cover on the rear
panel.
