Xantrex Technology XG 850 manual Using Multiple Power Supplies

	Using Multiple Power Supplies
Using Multiple Power Supplies
	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.
	CAUTION: Equipment damage	3
	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 3-5 on page 3–42. When using multiple supplies in series or parallel, they will not meet the single unit specifications in this Manual.
