   2	Front plate
   3	M6 rivet nuts

3. Before starting the assembly, insert the two M6 rivet nuts (2) on the front lifting brackets (1) using a rivet gun.

   NOTE: Follow the above step only if the rivet/insert nuts are not installed to the panel.
   

   1	Front lifting brackets
   2	M6 rivet nuts

4. To install the ventilation channel:

   1. Insert the ventilation channel (1) from the top of the cubicle into the circuit breaker compartment.

      

      1	Ventilation channel
      2	Pressure relief flap

      NOTICE
      HAZARD OF INAPPROPRIATE ASSEMBLY During the insertion of the ventilation channel, coordinate the pressure relief flap to their functional positions. Ensure the ventilation channel should not collide with the pressure relief flap during its insertion. Failure to follow these instructions can result in equipment damage.

      
      NOTE: In case an arc sensor (1) is present, the sensor cable can be routed through the hole (2) in the front plate (3), refer to below figure view A. Without the sensor, the cover should be flipped, which closes the hole (2) completely, refer to below figure view B.
