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 200 LED 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.
3. Replace a defective fuse with one of the same type and rating only. Replacement primary fuses are
available from Martin suppliers (P/N 05020013).
4. Check that the seal is in perfect condition, then reinstall the rear cover, gradually cross-tightening the
eight M6 screws working diagonally. Tighten to a maximum torque of 5 - 6 Nm (3.7 - 4.4 ft.-lbs.).
5. Reapply power.
