    Application




    Maintenance


    1. Dust: If too much dust, it will reduce the insulation level of the soft starter, even causes the soft starter does not work.
    Brush the dust with clean and dry brush.
    Remove dust with compressed air machine.
    2. Condensation: If condensation, it will reduce the insulation level of soft starter, even causes the soft starter does not work.
    (1) Blow it with a hair dryer or electric stove.
    (2) Bring it to power distribution room for dehumidification.
    3. Regularly check components' intact. Whether it can work properly.
    4. Check soft starter' cooling channel, ensure they are not clogged by dirt and dust.
    Before maintenance checking, it has to cut off all power in the line side of soft starter.
