(2) Wiring
! Do not fit capacitive equipment such as power factor correction capacitor, radio
noise filter or surge suppressor to the output of the inverter.
! The connection orientation of the output cables U, V, W to the motor will affect
the direction of rotation of the motor.
(3) Trial run
! Check all parameters, and ensure that the machine will not be damaged by a
sudden start-up.
(4) Operation
! When you have chosen the retry function, stay away from the equipment as it will
restart suddenly after an alarm stop.
! The [STOP] key is valid only when the appropriate function setting has been
made. Prepare an emergency stop switch separately.
! Make sure that the start signal is off before resetting the inverter alarm. A failure
to do so may restart the motor suddenly.
! The load used should be a three-phase induction motor only. Connection of any
other electrical equipment to the inverter output may damage the equipment.
! Do not modify the equipment.
! Do not perform parts removal which is not instructed in this manual. Doing so
may lead to fault or damage of the inverter.
