Noise And Impedance Effects; Making The Connections; Connecting Single Loads - Xantrex XKW 8-350 Operating Manual

Noise and
To minimize noise pickup or radiation, use shielded-twisted pair wiring of as short a
Impedance length as possible for load wires. Connect the shield to the chassis via a rear panel
mounting screw. Where shielding is impossible or impractical, simply twisting the

wires together will offer some noise immunity. When using local sense connections,
use the largest practical wire size to minimize the effects of load line impedance on
the regulation of the supply.
Making the
Connections
Make load connections to the power supply at the positive and negative output
terminals (or bus bars) at the rear of the power supply. See

CAUTION
!
When making connections to the bus bars, ensure each terminal's mounting
hardware and wiring assembly is placed to avoid touching the other terminal and
shorting the power supply output. Heavy connecting cables must have some form of
strain relief to avoid loosening the connections or bending the bus bars.
