4 Continue with section 8.4.4 Finishing Steps for remounting the
capacitors, adjusting the clamp pressure and installing the phase
module.
8.4.4 Finishing Steps
1 Insert the isolator disk and center it.
2 Remount the capacitors.
Proper alignment is important to prevent distortion and lateral forces
acting on the capacitors.
When tightening the nuts pay attention not to exceed the maximum
tightening torque (M8 nuts: 8 Nm).
Exceeding the maximum value may result in damage of the
capacitors.
3 Adjust the clamp pressure of the stack.
Insert the pressure adjusting bolt and tighten it until the clamp
pressure loading gauge is released.
4 Refit the clamp pressure loading gauge in its storage place.
5 Check the blocking/unblocking behaviour of the new diode. Refer to
Chapter 2 - Checking IGCTs and Diodes .
6 Remount the phase module in the cabinet following section
7.3
