Electric shock hazard:
The fuses are 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.
