Preparing the EUT
1. Set channel 1 of the DC power supply to 3 V, current limit 10 A.
2. DANGER! Do not connect the R&S ESH3-Z6 to mains voltage for the test. Con-
necting the R&S ESH3-Z6 to the mains voltage poses hazardous or even life-
threatening risks to the operator.
Arrange the test setup for X1.2 - X2.2 bolts as shown in
Fig. 2 .
The current conductors connect to output slots of power supply. The voltage refer-
ence conductors connect to the reference slots (signed SENSE) of power supply.
3. Tighten the torque of M8 nuts: 8 Nm to 10 Nm.
4. Turn on the DC power supply.
