5.3. 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 ). They are fuses of the "F"
type (fast-acting / quick-acting / fast blow / quick blow), European size 5x20 mm, ceramic or glass body
cartridge.
The fuses must be rated for a current corresponding to your mains nominal voltage:
•
6.3 A / 250 V for operation from 200-240 VAC;
•
10 А / 250 V for operation from 100-120 VAC.
Suitable fuses are:
•
For 200-240 VAC mains nominal voltage, e.g.:
- EATON Bussmann, PN: S-501-6.3-R (ceramic body cartridge);
- Littelfuse, PN: 021706.3 (glass body cartridge).
•
For 100-120 VAC mains nominal voltage, e.g.:
- EATON Bussmann, PN: S-501-10-R (ceramic body cartridge);
- Littelfuse, PN: 0217010 (glass body cartridge).
If, after Primary Mains Fuses replacement, the device does not operate normally, we
recommend repair, performed only by a trained service technician.
Contact your ACOM dealer for assistance (see Section
1.2 Owner Assistance
).
Besides the primary fuses, on the HV PCB and on the MAINS PCB (inside the amplifier) there are three fuses
which
are not replaced by the user . They are fuses of the "T" type (time-lag / slow-blow), European size
5x20 mm, ceramic (or glass) body cartridge, as follow:
•
1 x 0.8 A, 250 V (located on MAINS PCB);
•
1 x 2 A, 250 V (located on HV PCB);
•
1 x 5 A, 250 V (located on MAINS PCB).
Suitable fuses are:
•
0.8 A, 250 V, e.g.:
- EATON Bussmann, PN: S505-800-R (ceramic body cartridge);
- Littelfuse, PN: 0218.800 (glass body cartridge);
