ground
Disconnect all cables before moving
Moving the instrument without disconnecting the cable may result in damage to the cable or drop the
instrument during handling it.
1.3
Connecting AC Power Cables
The power cord is supplied by Sourcetronic along with the instrument.
Do not use an AC power cord
that is not included with the instrument.
Connection order:
1.
Make sure the power supply is within the power cord range of the instrument.
2.
Determine the nominal value of the instrument fuse, the fuse box is installed in the correct
position (power supply)
3.
Make sure the instrument's power switch is off
4.
AC power cord is connected to the AC LINE (AC power cable) end of rear panel.
5.
Please use the supplied AC power cord, or the AC power cord selected by the qualified
professionals
6.
Plug in an AC outlet
1.4
Grounding
!
Warning
Please make sure to connect the instrument to an electrical ground (safety ground, earth).
If the grounding of the power outlet is not connected to the peripherals or the ground of nearby
commercial wires, the instrument is not directly connected to the earth, and the chassis of the instrument
is charged with an excessively high voltage, which is very dangerous.
The instrument is a Class II device (the device is protected from electric shock in addition to the basic
insulation). However, there is still the possibility of electric shock if there is no proper grounding.
To ensure safety, it is important to ensure that the instrument is grounded.
Select at least one of the following two available methods to ground:
1.
The power cord is connected to a single-phase, three-wire power outlet. Make sure that
the socket’s ground wire is securely connected to the ground.
2.
Connect the protective terminal of the rear panel to the ground through a grounding bar
(a copper wire or copper bar with a reliable connection to the ground which a production
line is equipped). Have a dedicated engineer select, make, and install the ground cable.
Ensure that the ground connection is correct and reliable.

Operation Check
!
Warning:
During the normal operation, please use
INTERLOCK
to ensure the safety.
When using this tester in a cramped working space, make a box-like structure for the DUT; when
testing a complicated large-scale DUT: provide a cover or other means for the DUT to prevent electric
shock, cutting off the output when the cover is opened. It is also recommended that an enclosure be
provided around the operating area and that output be cut off every time the door is opened, to keep
the workplace safe and secure.
When the power switch is turned on, all the lights on the front panel lit on and begins a self-check to
make sure all indicators are working to ensure safety. It is particularly dangerous to conduct testing
when the
DANGER
indicator (high voltage hazard during testing) is damaged.
