( 2 ) Wiring
z
Do not fit capacitive equipment such as a power factor correction capacitor,
radio noise filter or surge suppressor to the output of the inverter.
z
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
z
Check all parameters, and ensure that the machine will not be damaged by a
sudden start-up.
( 4 ) Operation
z
When you have chosen the retry function, stay away from the equipment as it
will restart suddenly after an alarm stop.
z
The [STOP] key is valid only when the appropriate function setting has been
made. Prepare an emergency stop switch separately.
z
Make sure that the start signal is off before resetting the inverter alarm. A failure
to do so may restart the motor suddenly.
z
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.
z
Do not modify the equipment.
z
The electronic overcurrent protection does not guarantee protection of the
motor from overheating.
z
Do not use a magnetic contactor on the inverter input for frequent
starting/stopping of the inverter.
z
Use a noise filter to reduce the effect of electromagnetic interference. Otherwise
nearby electronic equipment may be affected.
z
Take measures to suppress harmonics. Otherwise power harmonics from the
inverter may heat/damage the power capacitor and generator.
