R&S
ESR
The R&S ESR can be used with different AC power voltages and adapts itself
automatically to it. Refer to the datasheet for the requirements of voltage and fre-
quency.
For safety information, see
To connect the AC power
1. Plug the AC power cable into the AC power connector on the rear panel of the
instrument. Only use the AC power cable delivered with the R&S ESR.
2. Plug the AC power cable into a power outlet with ground contact.
The required ratings are listed next to the AC power connector and in the data
sheet.
For details on the connector, refer to
nection and Main Power
3. Install the remaining cables before switching on the product.

Connecting to a DC Power Source (Optional)
You can equip the R&S ESR with the optional DC power supply adapter (R&S
FSV-B30) and connect it to a DC power source, for example a battery. The DC
power supply adapter allows you to operate the instrument with a DC voltage of
10 V to 28 V.
To connect the DC power
1. Install the DC power supply adapter to the R&S ESR.
For more information about the installation process, refer to the installation
guide delivered with the adapter.
Using external power supplies to supply the R&S ESR with DC safety extra
low voltage (SELV) can lead to physical injuries resulting from an electrical
shock.
To avoid physical injuries, make sure the requirements for reinforced or dou-
ble insulation are met, according to DIN/EN/IEC 61010 (UL61010, CAN CSA
C22.2 No. 61010) or DIN/EN/IEC 60950 (UL60950, CAN CSA C22.2 No.
60950). Use a cable with a maximum length of 3 m.
2. Connect an appropriate DC power cable to the DC power supply adapter.
3. Connect the cable to the DC power source.
