In addition to the DC output, there is a sense terminal which is ideally connected to the load line as
close as possible to the DUT. Alternatively, it can also be connected directly to the DC output in the
system. In this case the voltage drop across the output channels will not be compensated.
To avoid interferences, the sensor cables (twisted if possible) must be laid separately from power
cables and control cables and limited to the absolutely necessary length. For parallel-/ serial mode,
connect the sense in the same way as the DC output.

The device can be damaged, if the sense cable is not connected.

The load is connected to the DC output rails with correct polarity ("Output -" and "") using
shielded cables with sufficient current carrying capacity and dielectric strength. The connection is
prepared for M10 screws (accessory package reference 30a, washers, nuts 30b-d). For devices with
automatic channel switching mode, use M12 screws (accessory package Reference 31a, washers, nuts
31b-d). Make sure that the eyelets are flat and even. When connecting the device under test, make
sure that the cables are kept as short as possible. Long cables and loops have a negative effect on
the dynamic behavior of the ERS-system!

External voltage and current sources connected to the output should be fused externally to prevent
damage to the ERS by high fault currents.
