Maloperation
Removable voltage transformers are exclusively designed for operation with
specific protection fuse-links.
Use only the fuse-link types listed in the following table.

Tripped protection fuse-links can cause hidden damages on the other protection
fuse-links.
Always replace all protection fuse-links, even if only one protection
fuse-link has tripped.
