Wiring the Main Circuits
• Main Circuit Input Power Supply
Always connect the power supply line to input terminals R/L1, S/L2, and T/L3 (R/L1, S/
L2 for single-phase Inverters). Never connect them to terminals U/T1, V/T2, W/T3, B1,
B2, −, +1, or +2. The Inverter may be damaged if the wrong terminals are connected.
For single-phase Inverters, always use terminals R/L1 and S/L2. Never connect
terminal T/L3.
• Grounding (Use ground terminal .)
Always ground the ground terminal according to local
grounding codes.
Failure to observe this warning may result in an electric shock
or a fire.
Never ground the VS-606V7 to the same ground as welding machines, motors, or other
electrical equipment.
When several VS-606V7 Inverters are used side by side, ground each as shown in exam-
ples. Do not loop the ground wires.
