Xantrex Technology XPD 120-4.5, XPD 60-9, XPD 7.5-67 manual Using Multiple Supplies, Local Operation

Section 3. Local Operation

Using Multiple Supplies

Using Multiple Supplies

WARNING

There is a shock hazard at the load when using a power supply with a rated or combined output greater than 40 V. To protect personnel against accidental contact with hazardous voltages created by 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

Do not connect power supplies from different manufacturers in parallel or in series.

CAUTION

The remote programming inputs are internally referenced to the supply’s negative output. Do not connect remote programming ground lines (J210 terminal 8,13) to the supply’s positive output.

You can operate power supplies of the SAME MODEL with outputs in series or in parallel to obtain increased load voltage or increased current. Split supply operation gives you two positive outputs, or a positive and a negative output.
