1. Check nominal voltage of battery.
2. Only charge lead-acid batteries and lithium iron
phosphate batteries with a rated voltage of 12 V or
24 V.
"Fault no.: 40"
Possible cause:
No valid parameter set loaded.
Remedy:
1. Reload firmware.
DANGER – Risk of electric shock from live
parts. Observe the electrical engineering safety
regulations.
2. Connect customer service circuit board M1 to power
module 1 and BAT 690 check function.
