Electric shock hazard:
The fuse is an integral part of the overvoltage protection. When
fuse replacement is necessary, refer to “Specifications” for the
correct type, size and capacity. Using any other type of fuse will
void the overvoltage protection rating of the unit.
Failure to observe this warning could result in severe injury or
death.
