2-14 Installation and Preparation PLZ-U
■
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 fl ow 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.
• The buzzer sounds when a reverse voltage of approximately 0.6 V or greater is
applied.
