3.5.4 Module
Installation and Wiring
1. Before connecting the cables, please be sure to cut off the input power to avoid
accidents.
2. The SVG must be grounded properly to avoid any possible damage caused by current
leakage.
3. Check the diameter marking of SVG module’s input wires, and make sure the wire
diameter and phase sequence are correct. Please refer to
Figure 3-19
to perform
wiring and refer to
Table 3-2
for the specifications of the power lines.
(Figure 3-19: Main Power Cables Connection)

NOTE:
1. Wires with the temperature resistance up to 70
℃
(158
°
F) are used
for calculation of the above data.
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.
4. Connect the power wires from SVG cabinet power cable terminals to external breaker
or feeder, and finally, to the power supply system
(9~10N
ꞏ
m).
5. Check the marking of wires connecting the SVG module and the CT. Please make sure
the wire diameter and phase sequence are correct. Connect the input and output wires
of the CT according to
Figure 3-20
.
