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.
GOOD GOOD POOR
[Example of 3-phase,
400V class, 0.37kW
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.
