Introduction; Getting Assistance From Abb; Safety Notices; Safety In Installation And Maintenance - ABB ACS880+N5350 User Manual

This manual provides information needed for planning the installation, start-up, operating and servicing the ACS880+N5350
Cooling Tower Drive. The +N5350 control is designed specifically for Baldor-Reliance Interior Permanent Magnet Cooling
Tower Motor Control. Control is intended for operating cooling tower fans through a 10:1 variable speed range as well as
providing torque control to minimize mechanical stress on the system.
The information in this users guide supports Cooling Tower Drive Firmware V2.00.3.3 and ACS880 Drive Firmware V2.90.
This manual is a quick start guide and contains information on:
- Safety Instructions
- Installation and Wiring of the ACS880+N5350
- Programming the drive
- Reference to related manuals
The reader is expected to know the fundamentals of electricity, wiring, electrical components and electrical schematic
symbols.
The information supplied in this guide is intended to provide abbreviated information commonly needed to install and
commission the ACS880+N5350 for Cooling Tower Applications. For complete details please reference the full Hardware
and Software Manuals on the enclosed CD and available on www.abb.com.

1.1 Getting Assistance from ABB

For technical assistance, contact your local ABB representative. Contact phone numbers are located on the back cover
of this guide. Before calling, review the troubleshooting section later in this guide. You will be asked for the drive model
number or catalog number that is located on the nameplate along with the drive serial number.

1.2 Safety Notices

This chapter contains the safety instructions which you must follow when installing, operating and servicing the drive. If
ignored, physical injury or death may follow, or damage may occur to the drive, motor or driven equipment. Read the safety
instructions before you work on the unit.
USE of WARNINGS:
Warnings caution you about conditions which can result in serious injury or death and/or damage to the equipment and
advise on how to avoid the danger. The following warning symbols are used in this manual:
Electricity warning warns of hazards from electricity which can cause physical injury and/or
damage to the equipment.
General warning warns about conditions, other than those caused by electricity, which can result
in physical injury and/or damage to the equipment.
Electrostatic sensitive devices warning warns of electrostatic discharge which can damage the
equipment.

1.2.1 Safety in Installation and Maintenance

Electrical Safety -These warnings are intended for all who work on the drive, motor cable or motor.
WARNING: Ignoring the following instructions can cause physical injury or death, or damage to the equipment:
• Only qualified electricians are allowed to install and maintain the drive.
• Never work on the drive, motor cable or motor when main power is applied. After disconnecting the input power, always
wait for 5 minutes to let the intermediate circuit capacitors discharge before you start working on the drive, motor or motor
cable.
Always ensure by measuring with a multimeter (impedance at least 1Mohm) that:
• voltage between drive input phases L1, L2 and L3 and the frame is close to 0V.
• voltage between terminals UDC+ and UDC- and the frame is close to 0V.
• Do not work on the control cables when power is applied to the drive or to the external control circuits. Externally supplied
control circuits may cause dangerous voltages inside the drive even when the main power on the drive is switched off.
