Fuse�in�the�NOMOS�LS
To increase the operating safety of the NOMOS LS, the subwoofer is equipped with fuses at the signal
input mounted on the crossover. This fuse reduces the risk of consequential damage resulting from a
short circuit (i.e. charred cables / connectors / fire damage).
5.1
Replacing�the�Fuses
When the fuse is burned out, then the chassis is most likely already ruined, as the fuse just prevents
consequential damage resulting from a short circuit of the chassis. A replacement of the chassis is,
therefore, unavoidable.
Required�tools:
1. 3 mm Allen key for loosening the front grille
2. 3 mm Allen key for loosening the chassis
Instructions:
1. Remove the front grille.
2. Remove the speaker chassis.
3. Replace the fuse.
The fuse holder is mounted on the internal crossover.
Replace the fuse with the following original fuse only:
Bussmann�S�506-8A
4. Insert the (replacement) chassis.
First loosely fasten the screws for the chassis diagonal from one another, then tighten them. By
tightening the screws diagonally in two steps, a deformation of the chassis and thus a possible de-
centring of the voice coil can be avoided.
5. Mount the front grille.
