NOTICE
Damage to on-load tap-changer due to improperly carried out
solder connections!
Improperly carried out solder connections jeopardize safe operation.
► The connection contacts may not be shortened.
► The solder connection may only be produced on the end of the connec-
tion contacts (approx. 30 mm).
► Depending on the materials used, ensure the correct application of heat
to prevent both cold solder spots and thermal damage to the on-load tap-
changer.
► Ensure that sharp edges or points are not produced at the connection
points. These may cause a local concentration of the field strength and
therefore result in partial discharge.
► Remove flux material residue.
Taking these safety notices into consideration, you can establish the con-
nections in accordance with the supplied order-specified connection dia-
gram. This connection diagram also contains the exact assignment of the in-
dividual connecting pieces of the on-load tap-changer.
1. To do so, connect the leads for the tap winding and on-load tap-changer
take-off leads to the on-load tap-changer's connection contacts by means
of crimping or soldering, without twisting.
