NOTE:
1. Temperature endurance of above wires shall be 70°C (158°F).
2. If the Neutral line current of SVG is bigger than phase line current, the Neutral
line needs bigger diameter, please contact Delta service personnel.
3. For 3P3W model, configure 1.5 mm
2
wire on cabinet Neutral terminal is used
to supply phase voltage to cabinet AC fans.
4. If the SVG only outputs reactive current, the breaker size shown in
Table 3-1
should be multiplied by 0.8 ~ 0.9.
6.
Connect the power wires from SVG cabinet power cable terminals to external
breaker or feeder, and finally, to the power supply system.
