6.2. Cleaning
CAUTION
Do not use any solvents for cleaning. They may be dangerous to you and damage
amplifier surfaces, paint and plastic components.
Do not open the amplifier. Cleaning of the amplifier outer surface can be done with a piece of soft cotton
cloth lightly moistened with clean water.
Also, clean (as much as possible from the outside, without opening the amplifier) all ventilation apertures
on the cover and the chassis, including the ones on the bottom.
DANGER
Never push or put anything into holes in the case - this will cause electric shock.
6.3. Fuse Replacement
DANGER
If replacement of fuses is necessary, first pull out the amplifier mains plug from the
mains outlet and wait for at least 30 minutes!
NOTICE
For replacement, only use standard fuses from the types recommended below.
The two Primary Mains Fuses of the amplifier are located on the rear panel (see
Figure 2-1 Rear panel -
Connections
, Pos. (f)). They are fuses of the "F" type (fast-acting / quick-acting / fast blow / quick blow), size
1/4x1-1/4 inch (6.3 x 32 mm), ceramic or glass body cartridge.
The fuses must be rated for a current corresponding to your mains nominal voltage:
•
16 A / 250 V for operation from 200-240 VAC (15 A standard is also acceptable);
•
20 А / 250 V for operation from 100-120 VAC.
Suitable fuses are:
•
For 200-240 VAC mains nominal voltage, e.g.:
- EATON Bussmann, PN: BK/ABC-15-R (ceramic body cartridge);
- SIBA, PN: 70-059-60/16A (glass body cartridge).
•
For 100-120 VAC mains nominal voltage, e.g.:
- EATON Bussmann, PN: BK/ABC-20-R (ceramic body cartridge);
- SIBA, PN: 70-059-60/20A (glass body cartridge).
