  • Page 15 2NGA002471 A Unpacking, inspecting and storing 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 16 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.

  • Page 20 Mounting 2NGA002471 A 4.3.1 Detaching plug-in unit Before detaching the plug-in unit from the case, the auxiliary voltage must be disconnected. Turn off the power. Open the seal on the front panel by removing the sealing wire and screw the sealing screw all the way in.
  • Page 21 2NGA002471 A Mounting 4.3.2 Installing plug-in unit The protection relay is constructed in a way that a plug-in unit with voltage- or current-measuring inputs can only be plugged into a corresponding case. This prevents fitting an unsuitable plug-in unit into a wrong case. Before fitting the plug-in unit into the case, check that the unit and the case have the same serial number.
  • Page 22 Mounting 2NGA002471 A Lift the handle 90 degrees and push the plug-in unit into the case. Figure 9: Installing a plug-in unit into the case Let the handle swing down about 45 degrees. At the same time, push the plug-in unit into the case as far as it goes. Plug-in unit stops at about 7 mm (0.28 in) distance from the case.
  • Page 23 2NGA002471 A Mounting Turn down the handle to push the plug-in unit into its final position in the case.
