Safety information and use notice point
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 please consult with
producer.
(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
inverters breaks down.
1.3 Use Notice Points
(1) EDS300 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.
(5) For hoist and great inertia load, etc., the inverter would shut off frequently due to
over-current or over-voltage failure, in order to guarantee normal work, should
consider choosing proper brake package.
(6) Should switch on/off the inverter through terminal or other normal order
channels. It is prohibited that switch on/off the inverter frequently by using strong
electric switch such as magnetic control conductor, otherwise will cause the
equipment to be damaged.
(7) If need to install such switch as the magnetic control conductor, etc. between
(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.
