WARNING! Do not control the motor with an AC contactor or
disconnecting device (disconnecting means); use instead the
control panel (operator keypad) start (HAND ), AUTO )
and stop (OFF ) keys or external commands (I/O or
fieldbus). The maximum allowed number of charging cycles of
the DC capacitors (i.e. power-ups by applying power) is five in
ten minutes.
Note: For more technical information, contact your local ABB
representative (see page 441).
