C 11-3 (6) 3 Take off the clamp head to release the clamp pressure. Figure 11-2 Clamp Head The clamp head is fairly heavy and the DIU is not very well accessible particularly if installed in small CBUs. Due to the narrow space it is difficult to remove an IGCT while at the same time pushing up the components located above. Therefore it is recommended to remove the clamp head to facilitate work. The clamp disk and the isolators below the disk springs of the clamp head can also only be removed after the clamp head has been taken off. If the clamp head is not removed or pushed up far enough the centering pin below the disk springs will prevent the removal of clamp disk and isolators. The fixing bolts (see arrows in Figure 11-3) of the clamp bar require a 24 mm socket. Figure 11-3 Fastening Bolts Clamp bar Disk springs Centering pin Clamp disk Isolators Clamp head seen .
