Action
Safety
WARNING!
Obey the safety instructions during the start-up procedure. See ACS880 multidrives
cabinets and modules safety instructions (3AUA0000102301 [English]). If you ignore
the safety instructions, injury or death, or damage to the equipment can occur.
If you are not a qualified electrical professional, do not do installation or maintenance
work.
Prerequisites
The mechanical and electrical installation of the drive has been inspected and approved. See In-
stallation checklist (page 97).
The insulation resistance of the assembly has been checked according to instructions. See
Electrical installation (page 43).
The supply unit of the drive system has been started up according to the instructions in its
hardware manual.
Checks/Settings with no voltage connected
Do the steps listed in Electrical safety precautions (page 44). Refer to the hardware manual of
the supply unit for more information.
Check the settings of breakers/switches in the auxiliary circuits. See the circuit diagrams delivered
with the drive.
Disconnect any unfinished or uninspected auxiliary voltage (115/230 V AC) cables that lead from
the terminal blocks to the outside of the equipment.
Make sure that both channels of the Safe torque off circuit connected to the STO input of the
inverter control unit (A41) are closed. Refer to the wiring diagrams delivered with the drive.
With parallel-connected frame R8i inverter modules, make sure that the STO OUT output on the
inverter control unit (A41) is chained to the STO inputs of all inverter modules.
If the Safe torque off functionality is not used, make sure that the STO input on all inverter
modules is correctly wired to +24 V and ground.
Drives with Pt100 relays (option +(n)L506):
• Check the connections against the circuit diagrams of the delivery.
• Set the alarm and trip levels of the Pt100 relays.
Set the alarm and trip levels of the Pt100 relay as low as possible based on the operating temper-
ature and test results of the machine. The trip level can be set, for example, 10 °C higher than
what the temperature of the machine is at maximal load in the maximum environmental temper-
ature.
ABB recommends to set the operating temperatures of the relay, typically for example, as follows:
• 120…140 °C when only tripping is in use
• alarm 120…140 °C and trip 130…150 °C when both alarm and tripping are used.
Powering up the auxiliary circuit of the drive
Make sure that it is safe to connect voltage. Make sure that:
• nobody is working on the drive or circuits that have been wired from outside into the drive
cabinet
• the cover of the motor terminal box is in place.
Close the circuit breakers and/or fuse disconnectors supplying the auxiliary voltage circuits.
Close the cabinet doors.
Close the main breaker of the supply transformer.
Switch on the auxiliary voltage.
Setting up the inverter unit parameters, and performing the first start
Set up the inverter control program. See the appropriate start-up guide and/or firmware
manual. There is a separate start-up guide only for some control programs.
