Maintenance
This chapter describes the maintenance required for the softstarter. In principle, the product is
maintenance free but some items should be checked regularly.
Do not open the softstarter or touch any live parts when the main and control voltage
is connected.
9:1 Regular maintenance
• Check that all mounting bolts/screws are fastened. Tighten if necessary.
• Check that all connections of main, control and supply circuits are fastened.
• Tighten the terminal screws and bolts on the connection bars, if necessary.
• Check that the cooling airways are free from dirt and dust. If required, use pressurised air to clean.
• Check external filters. Clean, if necessary.
• Check that the fan is working and rotating freely. The blades should rotate without any resistance and
this can be checked at voltage free state.
• Check the real time clock and adjust if necessary.
In case of a fault or if a fault can not be reset, see Chapter 11, " Trouble shooting".
