1 Safety information and use notice points
2
1.2 Use range
(1) This inverter is only suitable for three phases AC asynchronous motor in general
industrial field.
(2) While applying inverter to such equipments that relate much to the life, great
property, safety devices etc., must handle cautiously, and consult with producer,
please.
(3) This inverter belongs to the control device of general industrial motor, if used in
dangerous equipment, must consider the security safeguard procedures when the
inverter breaks down.
1.3 Use notice points
(1) EDS780 series inverter is voltage-type inverter, so temperature, noise and
vibration slightly increasing compared to power source running when using,
belongs to normal phenomenon.
(2) If need to run for a long time with constant torque of low-speed, must select
motor of frequency conversion for use. Use general asynchronous AC motor
when running at a low speed, should control temperature of the motor or carry
on heat dissipation measure forcedly, so as not to burn the generator.
(3) Such mechanical device needing lubricating as the gearbox and gear wheel, etc.,
after running at a low speed for a long time, may be damaged as lubrication
result become poor, please take necessary measure in advance.
(4) When the motor running with frequency above specified, besides considering the
vibration, noise increase of the motor, must also confirm speed range of the
motor bearing and the mechanical device.
(1)
It is prohibited that connect AC220V signal to control ends except TA, TB,
TC, otherwise have danger of damaging property.
(2)
If the inverter is damaged or without all parts, please don't install and operate
it, otherwise have danger of fire or cause personnel to be injured.
(3)
When installing, should choose a place where can endure the inverter,
otherwise have danger of injuring personnel or damaging property while
falling down.
