slave(s). The Dynaload is supplied with two 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 any where between the power source and
the Dynaload. However, 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.
In a master/slave (parallel) configuration, S– must only be connected to the E– source at the
master Dynaload. The D connector cable(s) between master and slave(s) provides the S–
reference to the slave(s).
E– and E+ (Input)
E– and E+ are connected internally to the power input buses. They are to be used only as a
convenient connection point for the sense terminals when sensing the voltage locally.
