In any case time lag (slow blow) fuses 5x20 mm have to be used ! Usually the type of response is
abbreviated by a character on the metallic ring of the fuse: F (fast), M (medium) or T (time lag = slow
blow). A fuse coded "T" has to be used ! Medium or fast fast fuses are unsuitable and will blow. The
reason for the time lag fuses is the high transient current during power on that is ignored by the slow
fuses.
Even the A-100 DIY kit 1 contains a fuse. There is no difference between 115V and 230V for the fuse
value as the fuse is used to protect the secondary circuit of the supply (i.e. the low voltage). The
required value is 2.5A T (time lag / slow blow) and is valid for the transformers that are available from
us for the DIY kit.
Package
We strictly recommed to keep the original carton to have available a suitable package for the return
consignment e.g. in case of a repair.
Usage of the A-100 Cases
All A-100 cases are allowed only for the installation of A-100 modules or 100% compatible modules.
Especially the cases must not be used for the transportation of other goods (including the power cord
or patch cords)! Otherwise components of the cases may be damaged (e.g. power supply or bus
boards).
Installation
•
Do not expose the A-100 to rain or moisture.
•
Operation is allowed only in a dry environment in a closed room but not in the open country.
•
The installation near a large amplifier or other equipment which uses powerful mains transformers
may cause hum.
•
Do not install the A-100 in close proximity to equipment which produces an electromagnetic field
(monitors, computers, etc.), to avoid the possibility of mutual interference.
•
Do not connect the A-100 to a socket or outlet which is also being used by equipment such as
electric motors, lighting dimmers, etc, which can cause interference. Use a separate outlet for the
A-100.
•
Use in a dusty environment should be avoided.
Care and maintenance
•
Apart from cleaning the instrument, no other usermaintenance is recommended, of the modules or
system busses. Internal maintenance should be carried out only by qualified technicians.
•
For regular cleaning, use a soft, dry, or slightly damp cloth. To remove dirt, if necessary, use a
cloth slightly moistened with a very diluted mild detergent. This should be more than sufficient to
clean the instrument. Never use solvents like petrol, alcohol, or thinners.
