 t Insert the USB cable into the 
USB socket on the back of the 
display.
 t Feed the USB cable through the 
cable holders on the back of the 
scale.
3.5  Establishing the Power Supply
The scale is normally powered via the USB connection of your 
PC, which also supplies data for the scale. If this USB connec-
tion is not available, you can use AC adapter YEPS01-USB (see 
Chapter “6 Accessories,” page 8) for the power supply, 
which comes with different, country-specific mains adapters.
NOTICE
 − Ensure that the voltage rating printed on the AC adapter 
is identical to your local mains voltage (for connection 
data, see Chapter “7.1 General Data,” page 9).
 − If the stated supply voltage or the plug design of the 
power supply does not comply with your country's 
standard then please inform your nearest Sartorius 
representative.
Power supply via the AC adapter is only required:
 − When no PC or notebook is available.
 − In exceptional cases, when the output voltage of the USB 
interface of the PC or notebook is not sufficient.
AC adapter assembly is described in the following.
