5.1 Fastening on-load tap-changer to transformer cover

NOTICE

Damage to the on-load tap-changer and transformer!

Damage to on-load tap-changer and transformer due to electrical flashover
caused by insufficient distance from the motor-drive unit!

► When positioning the opening in the transformer, ensure a sufficient dis-

tance from adjacent energized parts.

Mount the on-load tap-changer horizontally with the sealing module on the
transformer cover.

Do not paint the surface on the underside of the transformer cover, which
later makes contact with the sealing module's o-ring. Only one coating of
primer is permitted.

1. Make opening for sealing module and holes for fixing screws in the trans-

former cover. The measurements and position can be found in the dimen-
sional drawing in the appendix.

2. Clean sealing surfaces on sealing module and underside of transformer

cover. Insert O-ring supplied in sealing module.

3.

 CAUTION!

 Gradually tighten screws crosswise as described below

without warping or deforming. Improper screw connection will result in
damage to the on-load tap-changer.

4. Guide on-load tap-changer from below through the opening in the trans-

former cover.

5. Evenly tighten screws crosswise by hand. Tighten screws crosswise with

a pre-tightening torque of 9 Nm.

6. Check seat of flange and seal for regularity.

7. Tighten screws crosswise with the full tightening torque of 16 Nm.

8. Tighten screws again with full tightening torque, working clockwise and

tightening one screw after another as far as each screw will go.

5.1.1 Attaching the ECOTAP® VPD® III

NOTICE

Damage to the on-load tap-changer and transformer!

The on-load tap-changer may only be operated in transformers that are
completely filled with insulating fluid. Non-compliance may result in voltage
flashovers that cause serious damage to the on-load tap-changer and trans-
former.

► Use in hermetic transformers with a gas cushion below the transformer

cover is only permitted with an appropriate special design.
