• Wiring the Main Circuit
• Main Circuit Input Power Supply
Connect the power supply wiring to input
terminals L1 (R), L2(S) and L3(T) [L1(R),
L2(S) for single-phase inverters]. Never
connect them to U/T1, V/T2, W/T3, -, +1,
or +2. Otherwise the inverter may be
damaged. Single-phase voltage may be
connected to inverter but do not use
terminal T/L3 for any other purposes.
• Grounding (Use ground terminal .)
Make sure to ground the ground terminal
according to the local grounding code.
Never ground the VS mini J7 to welding
machines, motors, or other electrical
equipment.
On Single-phase models, terminal
T/L3 is connected internally within
the inverter. Never use the terminal
for other purposes.
When several VS mini J7 units are used
side by side, ground each unit as shown in
examples. Do not loop the ground wires.
• Wiring the Main Circuit Terminals
Pass the cables through wiring hole and
connect. Be sure to mount the cover in its
original position.
Connect with a Phillips (plus)
screwdriver.
(Example of 3-phase,
200V class, 1.5kW
inverters)
