    Unpacking, inspecting and storing 2NGA001864 A Unpacking, inspecting and storing Removing transport packaging Protection relays require careful handling. Examine the delivered products to ensure that they have not been damaged during the transport. Remove the transport packaging carefully without force. Attach the protective film (supplied with the protection relay) on the top side of the unit for the installation phase.

  • Page 17: Inspecting Product And Delivery Items

    Returning a product damaged in transportation If damage has occurred during transportation, appropriate actions must be taken against the latest carrier. Inform the nearest ABB office or representative. ABB should be notified immediately if there are any discrepancies in relation to the delivery documents. Storing If the protection relay is stored before installation, it must be done in the original transport packaging in a dry and dust free place.
