The secondary fuses are inside the control unit. The control unit must first be
removed from the mechanical part to replace the fuses. To do this, loosen screws
1, 2, 3 and 4 and the M4 screws 5 and 6 at the bottom of the device and then
remove the cable connections between the mechanical part and the control unit.
