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 the ACS550 User’s
Manual for complete information.
Prepare for Installation
Warning! The ACS550 should ONLY be
installed by a qualified electrician.
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.
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 plate for later use in the ACS550
startup:
• Voltage __________________________
• Nominal motor current ______________
• Nominal frequency _________________
• Nominal speed ____________________
• Nominal power ____________________
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.
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
1. Position the ACS550 and
use screws or bolts to
securely tighten all four
corners.
2. Attach a warning sticker
in the appropriate
language on the inside
plastic shell.
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 screen so that
the screen can be
twisted into a pig-
tail. Keep the short
pig-tail short to
minimize noise radiation.
5. Route both cables through the clamps.
6. Strip and connect the power/motor wires, and
the power ground wire to the drive terminals.
See below, or “Power Connections” in User’s
Manual.
7. Connect the pig-tail
created from the motor
cable screen.
8. Install conduit/gland
box and tighten the
cable clamps.
Warning! For floating networks remove
screws at EM1 and EM3 on Frame sizes
R1…R4.
