ACS850-04 drive modules (160 to 560 kW, 200 to 700 hp)

circuit boards:

• Wear a grounding wrist band when handling the boards. Do not touch the boards unnecessarily. The printed circuit boards contain components sensitive to electrostatic discharge. 

WARNING! Ignoring the following instructions can cause physical injury or death, or damage to the equipment:

• Before adjusting the drive and putting it into service, make sure that the motor and all driven equipment are suitable for operation throughout the speed range provided by the drive. The drive can be adjusted to operate the motor at speeds above and below the speed provided by connecting the motor directly to the power line. 

• Do not activate any automatic fault reset functions of the drive control program if dangerous situations can occur. When activated, these functions will reset the drive and resume operation after a fault. 

• Do not control the motor with an AC contactor or disconnecting device; instead, use the control panel keys and , or commands via the I/O board of the drive. The maximum allowed number of charging cycles of the DC capacitors, ie, power-ups by applying power, is five in ten minutes.

Note: 

• If an external source for start command is selected and it is ON, the drive will start immediately after an input voltage break or fault reset unless the drive is configured for 3-wire (a pulse) start/stop.

• When the control location is not set to local, the stop key on the control panel will not stop the drive.
