Even though there is an automatic fuse in the instrument it is VERY IMPORTANT
to use an external fuse (max. 3A). Power supply cables should use a minimum of
0.5 mm² wires. To prevent damage to the LX8000 digital unit after a short circuit
on the RS485 bus there is an automatic fuse.
If a short circuit occurs then the 57 mm unit will appear not to work anymore. The reason is
not the defect of 57 mm unit – it is due to the hot automatic fuse. Turn off the LX8000
system and wait for the automatic fuse to cool down.
8.1 Installing the LX8000
Prepare the cut-out in the instrument panel according to the drilling template. For best
viewing angle consider installing the LX8000 into position which will meet requirements
shown on picture below.
Position the LX8000 digital unit in the cut-out in the instrument panel. Tighten the LX8000
digital unit with attached 2.5 mm screws.
When installing the LX8000 it is not necessary to remove the rotary knobs.
The mounting template is shown in the picture below (not to scale!):
The V5 vario unit should be mounted in a standard 57 mm hole.
