Section 3. Load Connection and Sensing
Grounding
Grounding
Make proper ground connections to avoid developing paths between separate ground
points. To avoid ground loops, there must be only one ground return point in a power
system. If the load itself is not grounded, ground the positive or negative output to
the supply’s chassis using a rear panel screw or the front panel ground binding post.
Local Sensing
Output voltage can be sensed from both the rear panel and the front panel output
connectors. Default local sensing regulates the voltage at the power supply output
terminal. Use remote sensing (see
“Remote Sensing” on page 19 ) when the voltage
needs to be regulated at the load rather than at the power supply output terminals.
Without sense line connections, the supply regulates the voltage at the output
terminals of the power supply. For improved local sensing, connect jumpers between
the sense terminals and the output terminals. See
Figure 3.2 and Figure 3.3 .
See Figure 1.1, “Front Panel Controls”, and Figure 1.3, “Rear Panel”, for sense
terminal locations on the front and rear panels.

WARNING
Disconnect the AC input before installing or removing jumpers.
Low Voltage Models Two barrier strip jumpers are shipped unattached with 15 V
and 30 V models. If your application requires precisely regulated output voltage at
the rear output terminals, install the jumpers as noted below.
1. Use a flat-bladed or #2 Phillips screwdriver to loosen the four terminal screws at
the output barrier strip.
2. Slide the jumpers under the screws.
3. Tighten the screws to the barrier strip. See Figure 3.2 .
