Fuse replacement
DANGER! Lock out power to the entire distribution system before servicing or opening any
cover. Replace fuses with ones of the same type and rating only.
Primary fuse
Exterior 400 Range fixtures are protected by a 2.5 amp slow-blow primary fuse located on the power PCB.
If a fixture is completely dead, the primary fuse may have blown.
To replace the primary fuse:
1. Isolate the fixture from power and allow to cool for 20 minutes.
2. Open the rear cover (see Figure 8 on page 13).
3. Replace a defective fuse with one of the same type and rating only. Replacement primary fuses are
available from Martin suppliers (P/N 05020010).
4. Reinstall the rear cover as follows:
a. Read“Managing humidity” on page 7.
b. Check that the seal is in perfect condition.
c. Place the seal and cover in position and drive the cover screws until they are finger-tight only.
d. Cross-tighten the screws evenly in a diagonal pattern, increasing torque gradually in stages to a
maximum torque of 8 Nm (5.9 ft.-lbs.).
5. Reapply power.
