S– and S+ (Voltage Sense)
There are two S– terminals and one S+ terminal. The S– and S+ (Sense Negative and Sense
Positive) terminals are used to sense the load voltage. The connection of a remote voltage sense
device to the S– and S+ terminals is illustrated in .
CAUTION:
Do not attempt to connect these inputs as the load inputs,
internal damage may occur.
S– and S+ (Voltage Sense) Wiring Tips
The S– and S+ terminals may be connected at the back of the Dynaload, or remotely at the
source. In any single or multiple load system, S– should be connected to E– (or the negative of
the source)
at one and ONLY one point .
CAUTION:
Damaging current loops could result from multiple connections to E–.
The Dynaload is supplied with two (2) metal straps between the S–, E– terminals and between
the S+, E+ terminals on the terminal strip. These are to facilitate voltage sense wiring when
sensing locally.
The S– and S+ external sense leads can be connected anywhere between the power source and
the Dynaload. It is recommended that the voltage sense wires are connected to the power source
terminals. This will eliminate potential errors due to voltage drop in the cable. It is also
recommended to use shielded wire for remote voltage sense leads to prevent external noise from
being introduced into the system.

E– and E+ (Input)
E– and E+ are connected internally to the power input terminals. They are to be used only as a
convenient connection point for the sense terminals when sensing the voltage locally.
