Connecting the power cord
1.
Confirm that the switch of the AC power distribution box is off.
2.
Confirm that the power switch is in the OFF position and verify that there is
no dangerous voltage on the connection terminals.
3.
Remove the protective cover outside the AC input terminal on the rear panel.
4.
Connect one end of the power cable’s round terminal to the AC power input
terminal on the instrument’s rear panel.
a)
You only need to connect the red/green/yellow (or brown/black/gray)
live wires to the terminals on the rear panel, which are not required to
correspond to L1, L2 and L3 terminals one by one.
b)
The yellow-green wire is grounding wire, which is connected to the
protective grounding terminal (PE).
5.
Mount the protective cover back to its original position.
6.
Refer to the suggestion connection diagram, connect the other end of the
power cable to the required AC distribution box.
2.4 Connecting Test Lines ( Optional)
Test lines are not standard accessories of the instrument. Please select optional
red and black test lines for individual sales based on the maximum current value.
For specifications of test lines and maximum current values, refer to
“
Specifications of Red and Black Test Lines
” in “
Appendix
”.
⚫
Before connecting test lines, be sure to switch off the instrument.
Power switch is in Off position. Otherwise, contact with output
terminals in rear panel may cause electrical shock.
⚫
To avoid electrical shock, before testing, please make sure the
rating values of the testing lines, and do not measure the current
that higher than the rating value. All test lines shall be capable of
withstanding the maximum short circuit output current of the power
supply without causing overheat.
⚫
If several loads are provided, each pair of load wires shall safely
withstand the rated short circuit output current of the power supply
under full load.
⚫
Always use test lines provided by ITECH to connect the equipment.
If test lines from other factories are used, please check that the test
line can withstand maximum current.
Specification for Test Cables
Test cables are not standard accessories for the instrument. Please select
optional red and black test cables for individual sales based on the maximum
current value. For specifications of test cables and maximum current values,
refer to
A.1 Specifications of Red and Black Test Cables
for more information.
Connecting the DUT (Local Measurement)
The instrument supports two kinds of wiring methods with the DUT: local
measurement and remote measurement (SENSE). The default test mode is
