Fuse replacement The printed circuit boards in the D-MAXE controller are static
sensitive devices. All standard ESD precautions must be
followed when touching or handling the printed circuit boards.
These fuses should be replaced by qualified personnel only.
Follow the instructions shown below for fuse replacement.
A common cause for blown fuses is an incorrect power supply
connection - especially reversed polarity. Before applying power
after replacing fuses, verify correct power supply wiring per
Figure 3.7:
If the units will not power on after fuses are replaced and correct
power supply connections have been verified, the units must be
returned to Maxcess for repair.
