4. Wiring

 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.

Never ground the VS mini to the same ground as welding machines, motors, or other elec-

trical equipment.

When several VS mini Inverters are used side by side, ground each as shown in examples.

Do not loop the ground wires.
