Please review the following safety precautions carefully to avoid personal
injury or damage to this product or any product connected to it. To prevent
potential danger, please use the instrument as specified.
Use proper power cord
Only the power cord designed for the instrument and authorized by local
country could be used.
Power supply
AC Input Voltages: 110V/220V ±10%, 50/60Hz.
Use proper fuse
- The fuse types: 110V/220V: T315mA/250V.

Observe all terminal ratings
To avoid fire or electric shock, please observe all ratings and symbols on theinstrument. Read this guide carefully to learn more details about the ratings
before connection.
Keep proper ventilation
Inadequate ventilation may cause an increase of temperature, which willlead to further damage. Please keep proper ventilation and check the fan

WARNING
Before switching on the input power supply voltage, please
disconnect the power supply before setting the voltage selector To
the appropriate gear.

Table 1: AC input line power specifications
Please connect the power carefully by following the steps below:
1. Check the input power
Make sure that the AC line power to be connected to the instrument meetsthe requirements in Table 1.
2. Check the voltage selector at the rear panel
Make certain that the voltage selector setting located at the rear panel of theinstrument matches the actual input voltage.
3. Check the fuse
When the instrument leaves the factory, the specified fuse is installed. Pleasecheck to verify the fuse matches the actual input voltage according to the"Input Power Requirements" on the rear panel of the instrument.

To Power on the instrument
After the instrument is connected to the power source, press the Power key
at the left bottom of the front panel to pwer on the instrument. When theinstrument is turned on, it will undergo a self-test. If the instrument passes
the self-test, the welcome interface is displayed; otherwise, self-test failure
information will be displayed. If this does occur please contact SIGLENT.

To replace the fuse, please follow the steps below:
1. Turn off the instrument and remove the power cord.
2. Insert a small straight screwdriver into the slot at the power socket andgently pry out the fuse seat.

CAUTION
Ensure that the AC selector setting on the rear panel of theinstrument matches the actual AC input voltage, otherwise, theelectronic load could be damaged.
Fuse Seat
CAUTION
Please pay close attention to the positive and negative polarities ofthe electronic load to avoid wrong connection. Otherwise, the load
could be damaged.

Fuse Replacement
The specifications of the fuse are relative to the actual input line voltage,shown in the table below. You can also refer to the rear panel “input powerrequirement”.

3. Adjust the power voltage selector manually to select the correct voltage
scale.
4. Take out the fuse and replace it with the specified fuse (for thecorresponding relationship between the input voltage and fuse specification,refer to the “input power requirement” on the rear panel).
5. Re-insert the fuse holder into the power socket (please pay attention tothe direction in which it is inserted).

WARNINGTo avoid personal injuries, unplug the power supply before replacing
the fuse. To avoid electric shock or fire, select the proper powersource settings and replace only with the proper fuse.

Trouble
Shooting
The following are some common failures and their solutions. If the problem persists after following the listed steps, please contact SIGLENT.
1. The instrument cannot power up.
(1) Check whether the power source is correctly connected.
(2) Check whether the power switch at the front panel is on.
(3) Remove the power cord and check whether the voltage selector is at the proper setting, whether the specification of the fuse is correct and whether the fuse isintact. If the fuse needs to be changed, refer to “To Replace the Fuse”.
(4) If the problem remains, please contact SIGLENT.
2. The USB device cannot be identified.
(1) Check whether the USB device is correctly working.
(2) Check whether the USB Host interface of the electronic load is correctly working.
(3) Make certain to use a Flash U-disk. This electronic load cannot support hard drive disk devices.
(4) Make certain to use FAT32 system format.
(5) Restart the electronic load then insert the USB device.
(6) If the problem remains, please contact SIGLENT.
3. The electronic load is working incorrectly.
(1) Check whether the input connection wiring is correct.
(2) Check whether the power is turned on.
(3) Check whether the value of the conduction voltage.
(4) Check whether the load settings for power, voltage and current meet the requirements.
(5) If the problem remains, please contact SIGLENT.
