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 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 0.2 A, 250 V;
• 2 x 2 A, 250 V.
Suitable fuses are:
• 0.2 A, 250 V, e.g.:
- Littelfuse, PN: 0215-200 (ceramic body cartridge);
- Littelfuse, PN: 0218.200 (glass body cartridge);
• 2 A, 250V, e.g.:
- EATON Bussmann, PN: S505-2-R (ceramic body cartridge);
- Littelfuse, PN: 0218002 (glass body cartridge).
WARNING
Do not replace fuses located inside the amplifier.
Blown internal fuses can be a symptom of a more serious problem, which should be
resolved beforehand. A fault of this type will not occur under normal operating
circumstances.
Replacing internal fuses is a complex and potentially dangerous operation.
For this reason, we recommend this work be carried out only by a trained service
technician.
Contact your ACOM dealer for assistance (see Section 1.2 Owner Assistance).
Unauthorized replacement of inside fuses infringes the warranty conditions!
Besides specific national standards, the principal fuses standard applied worldwide is
IEC 60127.
