Main circuit
L1/R, L2/S, L3/T
Main power supply input
Connect a three-phase power supply.
U, V, W
Inverter output
Terminals to connect three-phase motors.
P(+), P1
For DC reactor
connection
Connect a DC reactor (DCR) (option).
Be sure to connect if using motors with output of
75 kW or higher.
P(+), N(-)
For direct current bus
connection
Used for connection to direct current intermediate
circuits of other inverters and PWM converters.
P(+), DB
For braking resistor
connection
Connect braking resistor (DB) (option) terminal (+)
and DB (wiring length: 5 meters (16.4 ft) or shorter).
*G
For inverter chassis
(case) grounding
This is the grounding terminal for the inverter chassis
(casing) and motor. Ground to the earth at one end,
and connect to the motor grounding terminal at the
other end. Two of these terminals have been
provided.
R0, T0
Control power auxiliary
input
If wishing to retain the integrated alarm signal issued
if the protective function is triggered even when the
inverter main power supply is cut off, or to constantly
display the keypad, connect this terminal to the power
supply (FRN0008G2S-2G or higher / FRN0004G2□-
4G or higher).
Wire in the following order.
(1) Inverter grounding terminal (*G)
(2) Inverter output terminals (U, V, W), motor grounding terminal (*G)
(3) Direct current reactor connection terminals (P1, P(+))*
(4) Braking resistor connection terminals (P(+), DB)*
(5) Direct current bus connection terminals (P(+), N(-))*
(6) Main power supply input terminals (L1/R, L2/S, L3/T)
(7) Control power auxiliary input terminals (R0, T0) * (FRN0008G2S-2G / FRN0004G2S-4G or higher)
*: Connect if necessary.
