ACTION
Check power cable.
Replace fuses. Always disconnect from mains pow-
er before removing fuses. If the F3 fuse breakage
occurs again, and the control unit controls a High-
Speed motor, disconnect the B72/CL device (or the
B71/BCHP version HW 02 battery charger) from the
Battery Charger connector and see if it does not
happen again. If so, proceed with the replacement
of the device, which is damaged.
