ELS-304
Connections 2-3
(2) Load Cable
As shown in the Fig2-2-1, please use hexagon nuts and hexagon head bolts when you
connect load cables. Also please use load cables adapted for necessary current
capacity and wire the load cables as short as possible. In addition, twist the load
cables if the cable length is long and/or if possible.

* Negative effect by inductance
Back electro motive force caused by both inductance of load cable and internal
inductance of this product would influence rising time. Needless to say, current could not
be sunk if the voltage drop caused by the back electro motive force exceeds volt between
load terminals, because there is no volt. Potential difference left.
This product is designed to minimize the internal inductance but is not zero, so it is
necessary that some level of voltage potential difference need to be presented between
the load terminals. For example, 2V needs to be presented between the load terminals to
set and realize 50A/usec slew rate. Again, Voltage drop is caused by the inductance of
load cables, it is suggested that the inductance caused by load cables should be minimize
as much as possible.

The Inductance of the option Cable (LL-050) is 80nH (Typ), almost one fifth of
general cable (equivalent to the 7AWG).
