B&C Technologies SP Series Commercial - Manual (Page 35)

If controlling the AC drive with a parameter unit, the machines computer and
its safety features are bypassed. This could allow the basket to rotate at high
speeds with the door open. When using a parameter unit to control the AC
drive, a large sign should be placed on the front of the machine warning people
of the imminent danger.
Never touch terminals or components of the AC drive unless power is discon-
nected and the ”‘CHARGE”’ indicator LED is off. The AC drive retains potential
deadly voltage for some time after the power is disconnected. There are no user-
serviceable parts inside the AC drive. Tampering with the drive will void the
warranty.
Dangerous voltage are present in the electrical control boxes and at the motor
terminals. Only qualified personnel familiar with electrical test procedures, test
equipment, and safety precautions should attempt adjustments and troubleshoot-
ing. Disconnect power from the machine before removing the control box cover,
and before attempting any service procedures.
