MICROgarde controller I and II
04.20.11.18
Internal fuse rating
The MICROgarde main logic PCB is fitted with fuse protection marked FU1. In case of
failure FU1 should be replaced with a 1A Anti-surge, 20mm Fuse (TDSi part number 2021-
0030).
Lithium cell
A Lithium cell is fitted in a battery holder on the MICROgarde main logic PCB and will
support the memory and Clock functions for a maximum of 10 years in normal environmental
conditions. The cell will not normally need to be changed during the normal life of the
product, but may need to be replaced if the unit is left un-powered for very long periods. The
Lithium cell used is a type CR2032 (TDSi part number 2020-0015)
If it is necessary to change the cell, ensure that it is fitted correctly as shown in the diagram
below:
CAUTION! DANGER OF EXPLOSION IF CELL IS INCORRECTLY REPLACED!
