Prepare the UPS for Internal Busbar Connection

  1. Reposition the PE busbar in the UPS:
    1. Disconnect the EMC cable, the EMC cable holder and the bonding cables from the PE busbar. Note the connection of the cables on the ground busbar.
    2. Remove and discard the copper busbar.
    3. Move the PE busbar to the new position.
    4. Hold onto the EMC cable holder and pull gently on the end of the EMC cable to extend the length. Reconnect the EMC cable to the PE busbar.
    5. Reconnect the bonding cables to the PE busbar.
  2. Only for UPS with the plastic box as a separate part: Bend the M zone flaps upwards on the plastic box. This is necessary to make room for the internal busbars between the maintenance bypass cabinet and the UPS. Skip this step if the box is integrated in the inner door of the UPS. The integrated box does not need modification to fit with the internal busbars.
