Danger!
Hidden damage possible after blowing of fuses
The baseboard ( 68) is protected by a fuse which will be damaged if the
voltage applied is too high.
Possible consequences:
ƒ The device can be damaged if a non−approved fuse is installed.
ƒ In the event of a blowing fuse, hidden damage on the device cannot be ruled
out. Faultless operation can no longer be guaranteed.
Protective measures:
ƒ The fuse may only be replaced by an approved type.
ƒ In the case of safety−critical applications the device has to be checked by
Lenze after the blowing of fuses.
Approved types:
ƒ Littelfuse, series 154, 4 A
