Using the line contactor

Proceed as follows:

  1. Always place the line contactor before the line filter (if present).
  2. Use at least one contactor of utilization category AC‑3 (EN 60947-4-1) as a line contactor.
  3. NOTICE! Failing to observe the minimum switch-off time of the line contactor can cause material damage. Irreparable damage to the inverter or unforeseen malfunctions. After switching off the voltage supply, keep it switched off for at least 10 s.
    • With 3-phase devices, do not switch on the voltage supply more frequently than once every 60 seconds.
    • With 1-phase devices, do not switch on the voltage supply more frequently than once every 120 seconds.
  4. Do not use the line contactor for jog mode, but only for switching the inverter on and off.
