| WARNING: Shock hazard |
|
|
| There is a shock hazard at the load when using a power supply at an output of |
|
|
| greater than 40V or a combined output of greater than 40V. To protect personnel |
|
|
| against accidental contact with hazardous voltages created by a series |
|
|
| connection, ensure that the load, including connections, has no live parts which |
|
|
| are accessible. Also ensure that the insulation rating of the load wiring and |
|
|
| circuitry is greater than or equal to the maximum or combined output voltage of |
|
|
| the power supply. |

| Do not connect power supplies from different manufacturers in parallel or in |

| series. |

CAUTION: Equipment damage
The remote programming inputs are internally referenced to the power supply's negative output. Do not connect remote programming ground lines to the power supply's positive output.
You can operate power supplies of the same model with the outputs in series to obtain increased load voltage or with the outputs in parallel to obtain increased current, also called current sharing. Split supply operation gives you two positive outputs, or a positive and a negative output. See Figure
