• Wiring the Main Circuit
• Main circuit input power supply
Connect the power supply wiring to input
terminals L1 (R), N/L2(S) and L3(T)
[L1(R), N/L2(S) for single-phase
specifications]. Never connect them to U/
T1, V/T2, W/T3, B1, B2, -, +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-606V7 in common
with welding machines, motors, or other
electrical equipment.
When several VS-606V7 units are used
side by side, ground each unit as shown in
examples. Do not loop the ground wires.
NOTE
Single-phase (200V class, 0.75kW
or less) voltage may be connected
to terminal T/L3. Never use the ter-
minal with other purposes.
• Braking resistor connection
(optional).
To connect the braking resistor, cut the
protector on terminals B1 and B2.
To protect the braking resistor from
overheating, install a thermal overload
relay between the braking resistor and the
inverter. This provides a sequence which
shuts off the power supply, by a thermal
relay trip contact.
Use this same procedure when connecting
a braking resistor unit. Refer to page 104.
• Inverter output
Connect the motor terminals to U, V, W.
Wiring the main circuit terminals
Pass the cables through wiring hole and
connect. Be sure to mount the cover in its
original position.
