WARNING: Shock hazard
There is a potential shock hazard at the output when using a power supply with a
rated output greater than 60 V. Use load wiring with a minimum insulation rating
equivalent to the maximum output voltage of the power supply. For example,
select TEW, 105 °C, 600 V wiring for use with a 600 V, 1.4 A power supply.
For most connectors and jumpers, use any suitable wire such as 20 to
26 AWG stranded wire. For lowest noise performance, use shielded
twisted pair wiring of 20 to 26 AWG of the shortest length possible.
Ground the shield to pin J1.7 (analog common) on the Analog
Programming Connector or to the chassis via one of the Analog
Programming Connector screws.
