4.4 Assembling the circuit-breaker pole on the frame
Place a lifting sling around the breaking unit’s top as shown in Figure 4-5 and, using
this method, lift the circuit-breaker pole from its horizontal position in the transport
packaging.
Note the position of the lifting sling!
Check that the bolts (1) are tightened with tightening torque 60 Nm before lifting
the pole to vertical position
Figure 4-5. Lifting the circuit-breaker pole.
Check that the circuit-breaker
pole does not leak before
assembling on the frame.
1. Undo the sealing cap (1).
2. Press the non-return
valve’s disk (2) inwards
using a rod with a
diameter of about 5 mm.
A clear hissing noise
should be heard from the
pole. If no hissing noise
is heard, the pole leaks.
This must be rectified
before assembly.
3. Fit the sealing cap (1).
