2.6 When the SOURCE Terminal is Connected
Directly to Commercial Power Supply (AC Line)
Page 7-9
In directly connecting the SOURCE terminal to the commercial power supply (AC
line) without an AC power supply, such as when measuring rush current, use a
switch or circuit breaker that can disconnect this product from the commercial
power supply (AC line) (Fig.2-9) for safety.
•
You may receive an eclectic shock. To install a switch or circuit
breaker between the SOURCE terminal and commercial power
supply (AC line), be sure to shut off the power supply from the
switchboard by turning off the switches on the switchboard.
•
Set the current rating of the switch greater than the input current of
the EUT.
•
Use a bipolar switch circuit that can simultaneously shut off L and
N.
The L and N polarities of the LOAD and SOURCE terminals conform to IEC
standard measurement category CAT I or CAT II. This category depends on the
input voltage (Table 2-3).

Wire used, and terminal treatment
Table 2-4
Select the wire according to the input current of the EUT. Mount a cramping
terminal to terminate the wire. Use a cramping terminal that has a switch mounting
part with a hole diameter that fits the switch or circuit breaker.
