Interconnection Diagram with Varispeed G7
* 1. Do not connect a power supply to the Varispeed G7 AC power supply terminals R/L1, S/L2,
and T/L3.
* 2. For cooling fan terminals r/
1
and /
2
of the Varispeed G7 200 V class 30 to 75 kW models,
remove the jumper wiring between r/
1
and R/L1, and between /
2
and S/L2. Then take the
power supply for r/
1
and /
2
from the VS-656DC5 primary power supply line.
For cooling fan terminals r/
1
and 400/
2
400 of the Varispeed G7 400 V Class 55 to 300
kW models, remove the jumper wiring between r/
1
and R/L1, and between 400/
2
400 and
S/L2. Then take the power supply for r/
1
and 400/
2
400 from the VS-656DC5 primary
power supply line.
* 3. Be sure to use the specified AC reactor and harmonics filter for the VS-656DC5, to avoid
abnormal operations.
