Features and Specifications
Rear Panel Connectors and Switch
Making J2 Connections
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
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 of 16 to 24
AWG. Strip wires 0.26 in. (6.5 mm), insert, and tighten the wire clamp.

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.
WARNING
There is a potential shock hazard at the output when using a power supply with a
rated output greater than 40 V. Use load 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, 2 A model power
supply.
