Damage to the DC connectors due to the use of contact cleaner of other cleaning agents

Some contact cleaners or other cleaning agents may contain substances that decompose the plastic of the DC connectors.

  1. Do not use contact cleaners or other cleaning agents for cleaning the DC connectors.

Procedure:

  1. Ensure that the circuit breaker is switched off and that it cannot be reconnected.
  2. If an external DC load-break switch is installed, disconnect the external DC load-break switch from all voltage sources.

  3. Set the DC load-break switch of the inverter to position O.
  4. Measure the PV array voltage. Ensure that the maximum input voltage of the inverter is adhered to and that there is no ground fault in the PV array.
  5. Check whether the DC connectors have the correct polarity.

    6. If the DC connector is equipped with a DC cable of the wrong polarity, the DC connector must be reassembled. The DC cable must always have the same polarity as the DC connector.
