Common Information on Measurement Circuits
Prevent an Electric Shock with Terminal Cover
To prevent an electric shock, covers are attached to the LOAD and SOURCE terminals. Use
these terminals as shown in the figure below.
Performance of Input Terminals
●
Maximum input voltage
The maximum input voltage at the voltage input
terminal and current input terminal is 600 Vms/
900 Vpeak. This product cannot be used if the
maximum voltage is exceeded.
●
Maximum input current
The maximum input current at the current input
terminal is 40 Arms/100 Apeak. This product
cannot be used if the maximum current is
exceeded.
●
Instrument loss (input resistance)
The instrument loss (input resistance) of the
voltage input terminal is about 4.7 M

, and that
of the current input terminal is about 3.5 m

.
●
Measurement category
The voltage input terminal and current input
terminal conform to IEC standard measurement
category CAT I or CAT II. The measurement
category varies depending on the input voltage.
WARNING
• To prevent an electric shock, attach the terminal cover.
