MAC 401 Dual™ user manual
Fuse replacement
Warning! Disconnect from power before replacing a fuse. Replace fuses with ones of the same type
and rating only. Never bypass or bridge a fuse.
The MAC 401 Dual™ is protected by two 10 AT mains fuses located in fuseholders next to the power cable
entry (see Figure 1 on page 8).
To replace a fuse:
1. Isolate the fixture from power.
2. Use a flathead screwdriver to open the fuseholders and remove the fuses for testing or replacement.
3. Replace defective fuses with ones of the same type and rating only. Replacement fuses are available
from Martin.
4. Reinstall the fuseholders before reapplying power.
If a fuse blows repeatedly, disconnect the fixture from power immediately and consult your Martin supplier.
