2.4.2 Connecting EUT (Multi-outlet Unit)
When the EUT has a power cord with a plug, it cannot be connected directly to the
LOAD terminal. To connect devices with a wide range of plugs of various countries,
use the optional OT01-KHA multi-outlet unit. For details on the connection, refer to
the OT01-KHA Operation Manual.
•
To execute a test using the OT01-KHA multi-outlet unit according to harmonic
current test standard IEC 61000-3-2 (Ed5.0), (Ed3.0), (Ed2.2), JIS C61000-3-
2(2005) or JIS C61000-3-2(2019), input current of the EUT should be a
maximum of 5 A. Because the multi-outlet unit has impedance including the
contact resistance of the outlet part, attention must be paid to the requirements of
IEC Standard 61000-4-7 (voltage drop caused by wiring impedance) in a test
system.
2.4.3 Wiring Voltage Sensing Terminal (VOLTAGE SENSING)
The voltage sensing terminals are connected to the terminals of the EUT. Voltage
sensing includes the following:
• LOAD terminal sensing (setting at the time of shipment)
• Sensing at the connection end of the EUT
At the time of shipment, the LOAD terminal sensing is set. Voltage sensing
terminals N and V and ± and L have been short-circuited with the accessory wire kit
for short-circuiting the voltage sensing terminals. Voltage sensing should be used
with the setting at the time of shipment as much as possible.
Select the sensing at the connection end of the EUT when the voltage drop is
appreciable, for example, when the wire to the EUT is long. To measure the voltage
at the end of the EUT, connect the voltage sensing terminals directly to the EUT
(See Fig.2-7).
•
When long wires are used to connect the EUT with the LOAD terminals of this
product, the requirements of IEC Standard 61000-4-7 may not be met. Use the
system, minimizing the wire length 1.5 m or shorter is recommended.
