ABB AI880-1 DCS programming analog input unit
What this chapter containsThis chapter contains the installation checklist.
Checklist
Check the mechanical and electrical installation of the drive before start-up. Go
through the checklist below together with another person. Read the Safety
instructions on the first pages of this manual before you work on the unit.
Check
MECHANICAL INSTALLATION
The ambient operating conditions are allowed. See Technical data: Ambient conditions, IEC data or NEMA data.
The unit is fixed properly on floor and a vertical non-flammable wall. See Mechanical installation.
The cooling air will flow freely.
ELECTRICAL INSTALLATION See Planning the electrical installation, Electrical installation.
The motor and the driven equipment are ready for start. See Planning the electrical installation: Motor selection
and compatibility, Technical data: Motor connection.
The +E202 EMC filter capacitors are disconnected if the drive is connected to an IT (ungrounded) system.
The capacitors are reformed if stored over one year (refer to Capacitor reforming instructions (3BFE64059629
[English]).
The drive is grounded properly.
The mains (input power) voltage matches the drive nominal input voltage.
The mains (input power) connections at U1, V1 and W1 and their tightening torques are OK.
Appropriate mains (input power) fuses and disconnector are installed.
The motor connections at U2, V2 and W2 and their tightening torques are OK.
The motor cable is routed away from other cables.
Setting of the fan voltage transformer
There are no power factor compensation capacitors in the motor cable.
The external control connections inside the drive are OK.
There are no tools, foreign objects or dust from drilling inside the drive.
Mains (input power) voltage cannot be applied to the output of the drive (with bypass connection).
Drive, motor connection box and other covers are in place.

What this chapter contains
This chapter describes the start-up procedure and use of the drive.
Start-up procedure
1. Ensure that the installation of the drive has been checked according to the
checklist in chapter Installation checklist, and that the motor and driven
equipment are ready for start.
2. Switch the power on and set-up the drive control program according to the startup instructions given in the drive firmware manual.
3. Validate the Prevention of unexpected start-up function (option +Q950) according
these the instructions.
Action
Follow the safety instructions, see section Safety instructions on page 8-5.
Ensure that the drive can be run and stopped freely during the start-up.
Stop the drive (if running), switch the input power off and isolate the drive from the
power line by a disconnector.
Check the Prevention of unexpected start-up circuit connections against the circuit
diagram.
Close the disconnector and switch the power on.
Test the operation of the Prevention of unexpected start-up function when the motor is
stopped:
• Give a stop command for the drive (if running) and wait until the motor shaft is at
standstill.
• Activate the Prevention of unexpected start-up function and give a start command for
the drive.
• Ensure that the drive does not start and the motor stays at standstill.
• Deactivate the Prevention of unexpected start-up function.
4. Validate the Safe torque off function (option +Q967) according to the instructions
given in ACS800-01/04/11/31/104/104LC Safe torque off function (+Q967),
Application guide (3AUA0000063373 [English]).
