1 Safety information and use notice points
3
(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
inverter output and the motor, please guarantee the inverter is switched on/off
without output, otherwise may damage the inverter.
(8) The inverter may meet with mechanical resonance of the load within certain
range of frequency output, can set up jumping frequency to evade.
(9) Before using, should confirm the voltage of the power is within the working
voltage range allowed, otherwise should vary voltage or order special inverter.
(10) In the condition of altitude above 1000 meters, should use the inverter in lower
volume, reduce output current by 10% of specified current after each 1500
meters height increasing.
(11) Should make insulation check to the motor before using it for the first time or
after a long time placement. Please inspect with 500V voltage-type megohm
meter according to method shown as graph and insulation resistance should
not be smaller than 5 M
Ω
, otherwise inverter may be damaged.
(12) To forbid assembling capacitor for improving power factor or lightningproof
voltage-sensible resistance etc., otherwise will cause malfunction trip of the
inverter or damage of the parts, shown as graph 1-1.
(13)
Remind: EDS780 inverter require long-term work at full capacity, the customer
must have an external cooling fan, or it may overheat protection fault and affect
the frequency normal life! (Inverter output current below 4A, noneed to use an
external fan.)
