l
First remove the sense cable between sense and load terminals
l
Push in the orange release tabs with a small flat-blade screwdriver to release and insert the
sense wires.
l
Keep the sense wire size between AWG 16 (1.5 mm2) maximum and AWG 24 (0.2 mm2) minimum.
l
Strip thewire insulation back 10 mm.
Make your connections as shown in the following figure. Connect the load to the output terminals
using separate connecting wires. Keep the wire-pair as short as possible and twist or bundle it to
reduce lead inductance and noise pickup. Keep load leads under 14.7 meters (50 feet) per lead
because of inductance effects.
Connect the sense leads as close to the load as possible. Do NOT bundle the sense wire-pair together
with the load leads; keep the load wires and sense wires separate. Sense wiring can be of a lighter
gauge than the load wiring. The sense leads can carry up to 1 mA of current without degrading the
current measurement. Note however, that any voltage drop in the sense leads can degrade the
output voltage regulation. Try to keep the sense lead resistance less than about 0.5 Ω per lead (this
requires 20 AWG or heavier for a 50 foot length).
