refer to "Fuse Rating" on the rear panel or Table 1-2.

The electronic load supports two AC voltage ratings: 115 V and 230 V. Please

select the proper voltage scale based on the AC rating in your country.

When the switch lever is located at a different position, it indicates that a

different voltage rating is selected. When the switch lever is at the left, it

indicates that 230 V is selected. When the switch lever is at the right, it indicates

that 115 V is selected.

5. AC Power Cord Connector

AC power input interface. Plug the specified power cord available in the

accessories into the AC power cord connector of the instrument, and then

connect the instrument to the AC power.

CAUTION

Before connecting the AC power, please select the proper voltage

scale by using the AC selector.

6. Fuse

When leaving the factory, the instrument has installed a fuse that conforms to

the local standard. For fuse replacement, refer to "Fuse Replacement".

CAUTION

To avoid electric shock or fire disaster, please use the specified fuse

and ensure that no short circuit occurs to the fuse holder.

7. Fuse Rating

The required fuse rating is related to the actual input voltage, please refer to the

"fuse rating" on the rear panel of the load or refer to Table 1-2.

8. RS232 Interface

Serial communication interface. Use the 9-pin RS232 cable to build

communication with the PC to realize remote control.

9. USB Device

The instrument can be regarded as the "standby device" to connect to the

external USB device (e.g. PC) to realize remote control.

10. Voltage Monitoring Output Terminal

The voltage monitoring output terminal outputs the signal in analog quantity.

You can connect a device such as a digital oscilloscope through the terminal to

display the voltage output from the output terminal, so as to monitor the

changes of input voltage of the load.
