Action
Make sure that the main switch-disconnector [Q1.1] is switched off, or the main breaker [Q1] is racked
out.
Check that the grounding switch [Q9.1] (F259) is switched on.
Check the mechanical and electrical installation of the drive. See Installation checklist (page 135) .
Check the settings of breakers/switches in the auxiliary circuits. See the circuit diagrams delivered with
the drive.
Check the settings of the auxiliary voltage transformers (either internal or external).
Disconnect any unfinished or uninspected auxiliary voltage (115/230 V AC) cables that lead from the
terminal blocks to the outside of the equipment.
Check that both channels of the Safe torque off circuit connected to the STO inputs of both the supply
control unit [A51] and the inverter control unit [A41] are closed. Refer to the wiring diagrams delivered
with the drive.
Drives with ground fault monitoring for IT (ungrounded) systems (Q954): Adjust the settings of
the ground fault monitor to suit the installation. See the circuit diagrams of the delivery and
IRDH275B
Ground Fault Monitor Operating Manual by Bender (code: TGH1386en).
Drives with Pt100 relays ((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 temperature
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 temperature.
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.
Drives with an ACS880-1007LC cooling unit (as part of line-up or standalone): Do the start-up tasks
of the cooling unit. Refer to
ACS880-1007LC liquid cooling unit user's manual (3AXD50000129607
[English]) .
Drives with a voltmeter (G334): Make sure that the circuit breaker of the measuring circuit
(F5.1) is closed.
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 [Q21].
Drives of frame size 1×R8i + 1×R8i: Close the main switch-disconnector [Q1.1]. This will power up the
main circuit of the drive as well as the auxiliary voltage circuit.
Setting up the supply unit parameters
Check the voltage range setting in parameter 195.01 Supply voltage .
For more information on setting up the supply control program, refer to ACS880 IGBT supply control
program firmware manual (3AUA0000131562 [English]) .
If you need more information on the use of the control panel, refer to ACS-AP-I, -S, -W and ACH-AP-
H, -W Assistant control panels user's manual (3AUA0000085685 [English]) .
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.
Check that parameter 95.09 Switch fuse controller is set to Disabled .
