Wiring the Main Circuits
• Main Circuit Input Power Supply
Always connect the power supply line to input terminals L1, L2, and L3 of the input filter.
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 L and N of the input filter.
Never connect input terminals R/L1, S/L2, T/L3 of the inverter.
• Grounding (Use ground terminal
.)
Always ground the ground terminal
according to the
local grounding code.
Failure to observe this warning may result in an electric
shock or a fire.
Never ground the V7 IP65 to the same ground as welding machines, motors, or other elec-
trical equipment.
When several V7 IP65 Inverters are used side by side, ground each as shown in the follow-
ing examples. Do not loop the ground wires.
