Power Supply Options

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.

Table 1. Most Common Installation Option
Wiring Configuration Option for Five Wires: Line 1, Line 2, Line 3, Neutral, PE
		Grid type options: 400 V 3-phase Wye CAUTION Double check N connection is 230 V L to N at terminals of wirebox before energizing.

Note

Blue is used as the IEC standard for neutral. Some markets may use other colors to symbolize neutral and line conductors.

Table 2. 2nd Most Common Installation Option
Wiring Configuration Option for Three Wires: Line 1, Neutral, PE
		Grid type options: 230 V Line to Neutral CAUTION Double check N connection is 230 V L to N at terminals of wirebox before energizing.
