The converter module has a current limiting fuse on the high-voltage supply. Caution
must be exercised when checking this fuse. The procedure to replace the fuse is
outlined below:
1. Disconnect the mains from the entire system. This includes the A10, and
the converter module.
2. Disconnect the battery.
3. Disconnect the 6-way header that connects the converter module to the A10.
The converter module is now off, and the board is safe to handle.
4. Remove the fuse protection housing (If the housing is still in place).
5. Remove the fuse and replace it with a 5A, 250V, fast-blow fuse. (Dimensions
5x20mm).
6. Reconnect the 6-way header.
7. Reconnect the battery.
8. Reconnect the mains.
Upon reconnecting, if the converter module fails to function correctly in the event of a
power failure, refer to an installer or service technician.
