Single-phase inverter LK350E safety precautions

Mar 24, 2020

Safety Precaution:

  1. Before wring, please make sure that the input power is off.

  2. The wring work should be operated by the professional electrical   engineer.

  3.  The grounding terminals must be connected with the ground.

  4.  Having paused circuit wiring emergently, please make sure that the check is effective

  5. . Do not connect the output wire of the inverter with the shell, and pay   attention that the output wire should not be short-circuited.

  6.  Please check whether the voltage of the AC main circuit power is consistent with the rated voltage of the inverter.

  7.  Do not do the voltage withstand test on the inverter.

  8. Please connect the brake resistor according to the wiring diagram.

  9.  Do not connect the power to the U, V, W output terminals.

  10.  Do not connect the contactor with the output circuit.

  11. Mare sure to install a protection cover before power-on. When   removing the cover, be sure to make the power off.

  12.  If you want to reset the inverter with the retry function, do not get close to the mechanical equipment, because the inverter will restart suddenly   when the alarm stops

  13.  Confirmthat the operation signal is cut off. Before reset the alarm   device, or the inverter may start suddenly.

  14.  Do not touch the terminals of inverter, which are very dangerous   because there is high voltage on them.

  15.  When power is on, do not change the wiring and terminal.

  16.  Cut off the main circuit power before doing some check and maintain   work.

  17.  Do not arbitrarily reform the inverter.
