 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.
