Wiring the Main Circuit

MCCB or
leakage
breaker
L1 L2 L3
Grounding
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 152.
Inverter output
Connect the motor terminals to U/T1,
V/T2,W/T3.
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.

inverters]
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 terminal
U/T1,V/T2,W/T3, B1, B2, -, +1, or +2.
Otherwise the inverter may be damaged.
For single-phase inverters, always
use terminals R/L1 and S/L2. Never
connect to terminal T/L3.
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.
