ATTENTION: The sheet metal cover and mounting screws on the ASIC Board
that is on the power structure are energized at (-) DC bus potential high
voltage. Risk of electrical shock, injury, or death exists if someone comes into
contact with the assembly.
ATTENTION: Power must be applied to the PowerFlex® Active Front End to
perform the following start-up procedure. Some of the voltages present are at
incoming line potential.
To avoid electric shock hazard or damage to equipment, only qualified service
personnel can perform the following procedure.
Thoroughly read and understand the procedure before beginning.
During startup, if one of these pre-powerup checks reveals a concern, do not
proceed. Remove power including user-supplied control voltages.
User-supplied voltages can exist even when main AC power is not applied to the
PowerFlex Active Front End. Correct the malfunction before continuing.
