Caution 

● 

Do not touch the heat braking resistor, or other heat elements. These can become very hot. 

● 

Be  sure  that  the  motor  and  machine  is  within  the  applicable  speed  ranges  before  starting 

operation because the inverter is quite easy to run from lower speed to higher speed. 

● 

Do not check the signals on circuit boards while the inverter is running to avoid danger. 

● 

Be careful when changing the inverter settings. The inverter has been adjusted and set before 

ex-work. Do not adjust it wantonly. Please make proper adjustments according to the required 

functions. 

● 

Do consider the vibration, noise and the speed limit of the motor bearings and the mechanical 

devices when the inverter is running at or above the frequency of 50Hz.
