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.

CAUTION

To maintain the isolation of the power supply output and prevent ground loops, use an isolated (ungrounded) programming source when operating the power supply via remote analog control at the J2 connector.

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

WARNING

There is a potential shock hazard when using a power supply with a rated output greater than 40 V. Use wiring with a minimum insulation rating equivalent to the maximum output voltage of the power supply. For example, select TEW-105, 105 °C, 600 V wiring for use with a 600 V, 4 A model power supply.

For most connectors and jumpers, use any suitable wire such as 16 to 24 AWG stranded wire. For lowest noise performance, use shielded pair wiring. Strip wires 0.26 in. (6.5 mm), insert, and tighten the wire clamp.
