Overvoltage
Do not apply
voltage
exceeding the maximum
voltage of 150 VDC to the
load input terminal, as
it may cause damage.
The maximum
voltage that can be applied to the load
input
terminal
is 150
VDC.
Voltage exceeding the maximum
cannot be used.
If
overvoltage
is
applied,
an alarm
message appears along with
an alarm buzzer, and the load is turned off. If this hap-
pens,
immediately lower the
voltage of the equipment under test.
Polarity
If the polarity
of the
connection is reversed,
overcurrent will flow and may
damage the
PLZ-U or the
equipment under test.
Be sure to match
the polarities
between the load input
terminal and the
equipment
under test.
If the
polarity is reversed,
an alarm message
appears along with an
alarm buzzer.
Immediately turn off the
power to the
equipment under test.
NOTE]
•
The buzzer sounds
when a
reverse voltage of approximately 0.6
V or greater is
applied.
