PLZ-5W
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
specifications 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 specifications.
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 flows 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.
4
Attach the cover for the load input terminals on
the front panel.
5
Insert the load cables from the bottom and tight-
en the accessory knobs to fix the cables in place.

Connect the load cables to the output terminals
of the DUT.
Connect the positive (+) polarity of the load input terminal on
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, influences 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.

Connect the sensing cables to the PLZ-5W.
Use the screws to fix the
wires in place.
We recommend stripping

Connect the sensing cables to the DUT.
Connect the positive (+S) polarity of the SENSING terminal
to the positive (+) polarity of the DUT, and connect the neg-
ative (−S) polarity of the SENSING terminal to the negative
(−) polarity of the DUT. Connect the cables as close to the
EUT as possible.

To use remote sensing, you need to enable the remote
sensing feature. For details, see the User’s Manual on the
included CD-ROM.
