Making Load
Connections
Connections at the Front Panel Binding Posts
To make connections at the front panel, connect load wires using stripped wire
(0.6 in./15 mm), spade lugs, or banana plugs to the output binding posts.
For binding posts locations, see
Figure 1.1, “Front Panel Controls”
.
Connections at the Rear Panel Terminals
Low Voltage Models
To make load connections to low voltage models, attach an
appropriate gauge wire
1
following the steps below:
1. Strip load wires 0.75 in. (19 mm). An alternative is to attach tongue lugs (#6
stud) to the load wires, following the manufacturer’s instructions
.
2. Using a flat-bladed or #2 Phillips screwdriver, loosen the positive (
) and
negative (
) output terminal screws on the output barrier strip. See
Figure 3.2,
“Output Barrier Strip With Jumpers Installed”
.
3. Wrap stripped wire around the appropriate terminal screw. Tighten the screw.
High Voltage Models
To make load connections to high voltage models, attach
an appropriate gauge wire
1
(maximum #12 wire) following the steps below:
1. Strip load wires 0.6 in. (15 mm).
2. Using a 1/8 in. (4 mm) flat-bladed screwdriver, loosen the terminal screws on the
output terminal block. Insert wires into the output terminals (
, ) from the
bottom of the block. See
Figure 3.3, “Output Terminal Block With Jumpers
Installed”
.
3. Tighten the terminal screws.
Connecting
Multiple
Loads
Proper connection of distributed loads is an important aspect of power supply use. A
common mistake is to connect leads from the power supply to one load and then from
that load to other loads. In this parallel power distribution method, the voltage at each
load depends on the current drawn by the other loads, and DC ground loops develop.
Except for low current applications, we recommend that you do not use this method.
1. See
Table 3.1, “Current Carrying Capacity for Load Wiring,” on page 14
for the
correct wire gauge.
