and stop the AC motor drives by sending RUN and STOP commands through
the control terminals or the keypad. If you still need to run and stop AC motor
drives by turning the power ON and OFF, do so no more often than ONCE per
hour.
To comply with UL standards, connect the drive to a three-phase three-wire or
three-phase four-wire Wye system type of mains power system.
Output terminals of the main circuit
Use well-insulated motors to prevent any electric leakage from the motors.
Do NOT connect phase-compensation capacitors or surge absorbers at the
output terminals of AC motor drives.
When it is necessary to install a filter at the output side of the AC motor drive
terminals U/T1, V/T2, W/T3, use an inductance filter. Do NOT use phase-
compensation capacitors or L-C (Inductance-Capacitance) or R-C (Resistance-
Capacitance) capacitors.
Terminals for connecting DC reactor and DC bus
Use terminals [+1, +2] for connecting a DC reactor; use terminals [+1, +2/B1] for
connecting a DC bus.
When not in use, leave terminals +2/B1, (－) open.
Short-circuiting [B2] or [－] to [+2/B1] damages the motor drive. Do NOT short-
circuit those terminals.
Use these terminals to connect a DC reactor to improve the power factor and
reduce harmonics. A jumper is connected to these terminals at the factory.
Remove that jumper before connecting to a DC reactor.
