2. Wait about ten seconds until the green LED starts to blink off and on, which it will do five
times.
3. While the LED is blinking, remove the good fuse just installed. If the fuse is removed
during this flashing, the fuse position will go to a non-used status and no alarms will be
present. The LED will turn off and remain unlit until a new fuse is installed.
4. Return the removed fuse to its original location.
7 MAINTENANCE
7.1 Inspection
Inspect the fuse platform periodically (every six months is recommended) for damage to the
fuses and for damaged or broken wires on the power outputs and the external alarm
connections. Inspect for excessive dust and dirt that may block the vents.
7.2 Cleaning
If excessive dirt is found during the inspection, brush or wipe dust and dirt from the fuse
platform with a soft bristle brush or soft cloth. Take care not to not damage the fuses or any
wiring.
7.3 Fuse Removal
The GMT fuses can be removed with the aid of a wire hook or tweezers-type fuse puller. A fuse
puller is available as an accessory item. A TPA or KLM fuse may be removed by pulling the
fuses straight out from the fuse holders.
Caution: This equipment employs electrical voltage and amperage levels which may be
considered an electrical hazard. Care should be exercised to assure that only qualified
personnel are allowed to install, operate, maintain, or otherwise come in contact with this
equipment when the fuse platform is energized. Only insulated tools should be used on
energized elements of the fuse platform.
