WARNING! Do not control the motor with an AC contactor or
disconnecting device (disconnecting means); use instead the
control panel start and stop 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 three in
five minutes.
Note: For more technical information, contact the factory or your
local ABB representative.
