Note! This guide does not provide detailed installation, safety or operation instructions. See the 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 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.
Use the following chart to interpret the type code found on the drive label.
ACS550 - U1 - 08A8 - 4 + ...
AC, Standard Drive - 550 series
Construction (region specific)
01 = Setup / parts for IEC install./compliance
U1 = Setup / parts for US install./compliance
Output current rating
See Ratings in User’s Manual for details
Voltage rating
2 = 208 ... 240 VAC
4 = 380 ... 480 VAC
6 = 500 ... 600 VAC
Enclosure protection class/Options
No specification = IP 21 / UL Type 1 / NEMA 1
B055 = IP 54 / UL Type 12 / NEMA 12
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.
Tools Required
Screwdrivers, wire stripper, tape measure, mounting screws or bolts, and drill.
Collect Motor Data
Collect the following motor data from the motor nameplate for later use in the ACS550 startup:

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, and 25 mm (1 in) around the sides of the drive.
1.Mark the mounting points.
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
Note! Lift the ACS550 by its metal chassis.
1.Position the ACS550 onto the mounting screws or bolts and securely tighten in all four corners.
2.Non-English speaking locations: Attach a warning sticker in the appropriate language over the existing warning on the top
of the module.

Quick Start Guide
ACS550-U1 Drives (1 to 200 Hp)
UL Type 1 / NEMA 1 / IP21
Overview
The installation of the ACS550 adjustable speed AC drive follows the outline below.
Application
This guide provides a quick reference for installing
ACS550-U1 drives having a standard UL Type 1 (NEMA 1) enclosure.
Install the Wiring
Note! Use separate conduit runs for input power, motor and control 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 screen so that the screen can be twisted into a pig-tail. Keep the pig-tail short 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 pig-tail created from the motor cable screen to the GND terminal.
7.Strip and connect the power/motor wires, and the power ground wire to the drive terminals. See
diagrams below, or Power connections in User’s Manual.
8.Install conduit/gland box and tighten
the cable clamps.
Warning! For IT systems and corner grounded
TN systems, disconnect the internal EMC filter by removing screws: EM1 and EM3 (frame sizes R1-R4), or F1 and F2 (frame sizes R5-R6).
