NOTICE Damage to the on-load tap-changer!
Tap-winding connecting leads situated too closely to the change-over selec-
tor's moving parts block the change-over selector and therefore result in
damage to the on-load tap-changer.
► Tap-winding connecting leads in the area of the change-over selector
have to be routed such that they are at a sufficient distance from the
change-over selector's moving parts.
