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

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.

7.1Inspection

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.

7.2Cleaning

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.

7.3Fuse 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.
