Page 5: Use Of Warnings And Notes
General warning warns about conditions, other than those caused by electricity, which can result in physical injury and/or damage to the equipment. WARNING! The ACS550 adjustable speed AC drive should ONLY be installed by a qualified electrician. WARNING! Even when the motor is stopped, dangerous voltage is present at the power circuit terminals U1, V1, W1 and U2, V2, W2 and, depending on the frame size, UDC+ and UDC-, or BRK+ and BRK-.
Page 6 I/O board of the drive. The maximum allowed number of charging cycles of the DC capacitors (i.e. power-ups by applying power) is six in ten minutes. WARNING! The ACS550-01/U1 is not field repairable. Never attempt to repair a malfunctioning drive; contact the factory or your local Authorized Service Center for replacement.
