Start-Up And Operation - ABB ACQ810-04 Hardware Manual

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

Start-up and operation

These warnings are intended for all who plan the operation of the drive, start up or
operate the drive.
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 automatic fault reset functions 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 (disconnecting
means); instead, use the control panel or external commands via the I/O board of the
drive or a fieldbus adapter. The maximum allowed number of charging cycles of the DC
capacitors (i.e. power-ups by applying power) is one per two minutes. The maximum total
number of chargings is 100000 for frame sizes A and B, 50000 for frame sizes C and D.
Notes:
•
If an external source for start command is selected and it is ON, the drive will start
immediately after an input voltage break or a fault reset unless the drive is configured for
3-wire (pulse) start/stop.
•
When the control location is not set to local, the stop key on the control panel will not stop
the drive.
WARNING! The surfaces of drive system components (such as the mains choke)
may become hot when the system is in use.
