For basic operation, Wall Connector requires an electrical connection to
Line 1, Neutral, and Protective Earth (PE) terminals. Connection to Line 2 and Line 3
terminals is supported for some grid types.
CAUTION
Wall Connector supports 230 V L-N
(+/- 10%). Mis-wiring the neutral terminal with >264V to PE can damage Wall
connector
Wall Connector can operate on a three-phase power supply or a single-phase
power supply.
