Making J2 Connections

CAUTION

Do not attempt to bias program/monitor signal return (J2 terminals 5, 7, 9,
and 11) relative to the supply output because control ground (J2-3) and the
program/monitor signal returns are at the same potential as the power
supply return in a standard unit. Use the Isolated Programming (ISOL)
Interface option to allow control from a programming source at a different
potential relative to the supply’s output.

Make connections to the J2 connector using its screw-type wire clamps. Before making any connections, turn the
power supply OFF and wait until the front panel displays have gone out. You can unplug the connector from the
back of the unit in order to make it easier to install the required wiring.

Wiring

Use any suitable wire such as 16 to 24 AWG stranded wire for most connections, but we recommend that you
use shielded twisted pair wiring for applications which require low noise performance. Strip wires 0.26"
(6.5 mm) and insert securely as with any wire clamp connector.
