1. Fuse 48 V:
The 5A fuse (F801) “48V” protects all 48V in the system inclusive of Euromap from over
current.
This information is only for troubleshooting. Do NOT replace the fuse under any
circumstances.
In case of failure, ONLY replace the SCB with a new tested board.
2. Fuse 24 V:
2 x 5A fuses (F1001 and F1002) in parallel protect the DI/DO 24 V supply on the Safety
Control Board, whether the 24 V is from the controller or external power supply. Do NOT
replace the fuses under any circumstances. In case of failure ONLY replace the SCB with a
new tested board.
