2. Use hose clips to secure protective cover to horizontal drive shaft.

Figure 30: Securing protective cover

3. For special design types featuring cardan shafts, be sure to check the ex-

pansion bellows and the lubricant reservoir of the cardan shafts.

You will find a detailed description of how to fit the drive shaft in the MR op-
erating instructions "Drive shaft".

7.3.6 Centering on-load tap-changer and motor-drive unit

► Center on-load tap-changer and motor-drive unit as described in relevant

MR operating instructions for motor-drive unit.

7.4 Performing DC resistance measurement on transformer

The measured DC current is normally restricted to 10% of the rated current
of the measured transformer winding in order to prevent the winding from
overheating.
