ACS550

Quick Start Guide

ACS550-01 Drives (0.75…160 kW), 

IP21 / UL Type 1 Enclosure 

Overview

The installation of the ACS550 adjustable 

speed AC drive follows the outline below.

Application

This guide provides a quick reference for 

installing ACS550-01 drives having a standard 

enclosure.

Note: This guide does not provide detailed 

installation, safety or operational 

instructions. See ACS550 User’s Manual for 

complete information.

Prepare for installation

WARNING! The ACS550 should ONLY be 

installed by a qualified electrician.

Unpack the drive

Note: Lift the ACS550 by its chassis and not by its 

cover.

 1. Unpack the drive.

 2. Check for any damage. 

 3. Check the contents against the order / shipping 

label.

Check 

• Motor compatibility – Motor type, nominal 

current, frequency and voltage range must 

match drive specifications.

• Suitable environment – Drive requires heated, 

indoor controlled environment that is suitable 

for the selected enclosure. 

• Wiring – Follow local codes for wiring, circuit 

protection and EMC requirements.

Refer to User’s Manual and confirm that all 

preparations are complete.

Drive identification

Use the following chart to interpret the type 

code found on the drive label.

Collect motor data

Collect the following data from the motor 

nameplate for later use in the ACS550 startup:

• Voltage __________________________

• Nominal motor current ______________

• Nominal frequency _________________

• Nominal speed ____________________

• Nominal power ____________________

Tools required

Screwdrivers, wire stripper, tape measure, 

mounting screws or bolts and drill.

Prepare the mounting location

The drive requires a 

smooth, vertical, solid 

surface, free from heat and 

moisture, with free space for 

air flow – 200 mm (8 in) 

above and below.

 1. Mark the mounting points 

using the template.

 2. Drill the mounting holes.

Remove the front cover

 1. Remove the 

control panel, if 

attached.

 2. Loosen the 

captive screw 

at the top.

 3. Pull near the 

top to remove 

the cover.

Mount the drive

 1. Position the ACS550 and 

use screws or bolts to 

securely tighten all four 

corners.

Note: Lift the ACS550 by its 

metal chassis.

 2. Non-English speaking 

locations: Attach a 

warning sticker in the appropriate language 

over the existing warning on the top of the 

module. 

Install the wiring

Wiring power

 1. Open the appropriate 

knockouts in the gland box.

 2. Install the cable clamps for 

the power/motor cables.

 3. On the input power cable, 

strip the sheathing back far 

enough to route individual wires.

 4. On the motor cable, 

strip the sheathing 

back far enough to 

expose the copper wire 

shield so that the 

shield can be twisted 

into a bundle. Keep the 

bundle not longer than 

five times its width to minimize noise radiation.

– 360° grounding under the clamp is 

recommended for the motor cable to minimize 

noise radiation. In this case, remove the 

sheathing at the cable clamp.

 5. Route both cables through the clamps.

 6. Connect the bundle created from the motor 

cable shield to the GND terminal. 

 7. Strip and connect the power/motor wires and 

the power ground wire to the drive terminals 

using the torques given in the table below. See 

Power connections

 below or, for more detail, 

see User’s Manual.

 8. Install conduit/gland box and tighten the cable 

clamps.

WARNING! To disconnect the internal EMC 

filter, remove the screws marked with “

-

”, or 

replace the screws marked with “ ” with the 

provided polyamide screws, depending on 

the frame size.

 9. Install the cable clamp(s) for 

the control cable(s). (Power/

motor cables and clamps 

not shown in the figure.)
