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
1. Unpack the drive.
2. Check for any damage.
3. Check the contents against the order / shipping
• 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.

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 ____________________
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
2. Loosen the

Mount the drive
1. Position the ACS550 and
use screws or bolts to
securely tighten all four
Note: Lift the ACS550 by its

locations: Attach a
warning sticker in the appropriate language
over the existing warning on the top of the
Install the wiring
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
below or, for more detail,
see User's Manual.
