5.4.2.3 Change-over selector connection contacts for reversing change-over
selector connection
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.
The (+) and (-) change-over selector connection contacts are designed as
connecting lugs with through-holes for M10 screws for reversing change-
over selector connection.
The connection contact K is designed as an extended tap selector connec-
tion contact with through-hole for M10 screws.
1. Fasten the tap-winding connecting leads to the change-over selector in
accordance with the connection diagram provided. The cable shoes and
fastening materials are not included in the scope of delivery.
2. Take suitable measures to ensure that each fitting cannot come loose or
settle (e.g. by using clamping washers). Be sure to attach the screening
caps if these are included in the delivery scope.
