2.4 Output Connection
The output terminal block is located in the rear of the AC source. Load connecting to the "N"
and "L" is done at the output terminals. To meet the safety requirements, the safety cover
must be fastened. The wires to the load must be sufficiently large gauges, so they will not
overheat while carrying the output current. Please see Figure 2-3 on the next page.
Output terminal labeled "L" is the "+" terminal, terminal labeled "N" is the
"-" terminal when output voltage contains DC composition.
2.5 Remote Sense Connection
The remote sense function of the AC source monitors the voltage at the load instead at the
output terminal of the AC source. It ensures the delivery of accurate voltage as programmed
at the load by automatically compensating the output voltage drop over the connecting cable.
Remove the iron chip from the “S
N” and “SL” terminals, connect the remote sense to the load
as shown in Figure 2-3. Because the sensing leads carry only a few milliamperes, the wires
for sensing are much lighter than the load leads. The sensing leads are part of the feedback
path of the AC source, so they must be kept at a low resistance in order to maintain the best
performance. Connect the sensing leads carefully so that they will not be open-circuited. If
the sensing leads are left unconnected or become open-circuited during operation, the AC
source will disable the output. The sensing leads must be a twisted pair to minimize the
pickup of external noise. The sensing leads need to be connected to the load as close as
possible.
