2-4 Notes before use:
■F
ailure to observe the following warnings may cause serious damage to the inverter:
◆
Never connect the power cable (input) to the output port of the motor! Otherwise, serious damages may be
casued to the inverter!
◆
Do not connect the power input cable to any terminal other than R, S, T! Otherwise, serious damages may
be caused to the inverter!
◆
The output port of the inverter should never be connected to capactive loads! Otherwise, damages may be
caused!
■Failure to observe the following notes may shorten the lifespan of the device:
◆
Make sure to use the device in standard environments(including conditions related to temperature, humidity,
vibration, dust, water-drop, toxic gas, etc.).
◆
The lifespan of the inverter is highly impacted by the environment temperature, thus it is recommended to
use the device after environment temperature reduction.
◆
Please fully consider the size and ventilation conditions of the control cabinet when installing the inverter in
the control cabinet.
■Failure to observe the following notes may cause malfunction of the device:
◆
Please choose leakage protectors that can cope with higher harmonics and surges.
◆
A priori, no electromagnetic contactor should be installed between the inverter and the motor. Otherwise
excessive current may occur.
◆
Since the chracteristics of electromagnetic MCCB may change due to higher harmonics, please choose a
model with bigger capacity.
Please make sure to conduct examinations based on above warnings and notes, and to avoid the
inappropriate operations! Otherwise, irreparable financial loss may be caused!
