ABB ACH550-UH AC Drive Quick Start Guide
This guide provides a quick reference for installing ACH550-UH drives.
1. Prepare for Installation
Note: This guide does not provide detailed installation, safety, or operation instructions. See the ACH550 User's Manual for complete information.
Warning: The ACH550 should ONLY be installed by a qualified electrician.
Unpack the Drive
Note: Lift ACH550 by its chassis and not by its cover.
- Unpack the drive.
- Check for any damage.
- 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 a heated, indoor controlled environment 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, drill, and conduit hole punch (R5 and R6, IP 54 / UL Type 12 drives only).
Collect Motor Data
Collect the following motor data from the motor nameplate for later use in the ACH550 startup:
- Voltage
- Nominal motor current
- Nominal frequency
- Nominal speed
- Nominal power
2. 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.
- Mark the mounting points.
- Drill the mounting holes.
3. Remove the Front Cover
IP 21 / UL Type 1
- Remove the control panel, if attached.
- Loosen the captive screw at the cover's top.
- Pull near the top to remove the cover.
IP 54 / UL Type 12
- If a hood is present: Remove screws holding the hood in place.
- If a hood is present: Slide the hood up and off of the cover.
- Loosen the captive screws around the edge of the cover.
- Remove the cover.
4. Mount the Drive
IP 21 / UL Type 1
Note: Lift the ACH550 by its metal chassis.
- Position the ACH550 onto the mounting screws or bolts and securely tighten in all four corners.
IP 54 / UL Type 12
Note: Lift the ACH550 by its metal chassis.
The holes provided for access to the drive mounting slots require rubber plugs.
- As required for access, remove the rubber plugs. Push plugs out from the back of the drive.
- Position the ACH550 and securely tighten in all four corners.
- Re-install rubber plugs.
For non-English speaking locations: Add a warning sticker in the appropriate language over the existing warning on the top of the module.
5. Install the Wiring
Note: Use separate conduit runs for input power, motor, and control wiring.
General Wiring - IP 21 / UL Type 1
- Install thin-wall conduit clamps (not supplied) in the conduit/gland box.
- Install conduit/gland box.
General Wiring - IP 54 / UL Type 12
Frame sizes R1 - R4: Remove and discard the cable seals where conduit will be installed. (The cable seals are coneshaped, rubber seals on the bottom of the drive.)
Frame sizes R5 - R6: Use a punch to create holes for conduit connections as needed.
- For each conduit run, install water-tight conduit connectors (not supplied).
Wiring Power - IP 21 / UL Type 1
- Connect conduit runs to the box.
- Route input power and motor wiring through separate conduits.
- Strip wires.
- Connect power, motor, and ground wires to the drive terminals. Refer to "Power Connections" in the User's Manual for details.
Wiring Power - IP 54 / UL Type 12
- Route the power wiring through the conduit.
- Route the motor wiring through separate conduit.
- Strip the wires.
- Connect the power, motor, and ground wires to the drive terminals. Refer to "Power Connections" below or the User's Manual for more detail.
Warning: For floating networks, remove screws at EM1 and EM3 on frame sizes R1 - R4. Remove screws at F1 and F2 on frame sizes R5 or R6.
Wiring the Controls
- Route the control cable(s) through separate conduit.
- Strip the control cable sheathing and twist the copper screen into a pig-tail.
- Connect the copper screen pig-tail for digital and analog I/O cables at X1-1 (Ground only at drive end).
- Connect the ground screen pig-tail for RS485 cables at X1-28 or X1-32 (Ground only at drive end).
- Strip and connect the individual control wires to the drive terminals. The following shows the default configuration. Refer to "Control Connections" in the User's Manual for details or other configurations.
- Install the conduit/gland box cover (1 screw).
Control Connections (Default Configuration Example):
- X1-1: Signal cable shield (Digital/Analog I/O)
- X1-3: AGND (Analog input common)

6. Check Installation
Before applying power, perform the following checks:
- Installation environment conforms to the drive's specifications for ambient conditions.
- The drive is mounted securely.
- Space around the drive meets the drive's specifications for cooling.
- The motor and driven equipment are ready for start.
- For floating networks: The internal RFI filter is disconnected.
- The drive is properly grounded.
- The input power voltage matches the drive nominal input voltage range.
- The input power, motor, and control wiring are routed in separate conduit runs.
- NO power factor compensation capacitors are in the motor cable.
- The control connections are connected and tightened as specified.
- NO tools or foreign objects (such as drill shavings) are inside the drive.
- NO alternate power source for the motor (such as a bypass connection) is connected - no voltage is applied to the output of the drive.
7. Re-Install the Cover
IP 21 / UL Type 1
- Align the cover and slide it on.
- Tighten the captive screw.
- Re-install the control panel.
IP 54 / UL Type 12
- Align the cover and slide it on.
- Tighten the captive screws around the edge of the cover.
- Slide the hood down over the top of the cover.
- Install the two screws that attach the hood.
- Re-install the control panel.
Note: The control panel window must be closed to comply with IP 54 / UL Type 12.
Optional: Add a lock (not supplied) to secure the control panel window.
8. Apply Power
Always re-install the front cover before turning power on.
Warning: The ACH550 will start up automatically at power up, if the external run command is on.
- Apply input power.
When power is applied to the ACH550, the green LED comes on.
Before increasing motor speed, check that the motor is running in the desired direction.
9. Start-up
In Start-up, enter motor data (collected earlier) and, if needed, edit parameters that define how the drive operates and communicates.
Assistant Control Panel
The Start-up assistant steps through typical start-up selections and runs automatically upon initial power up. At other times, use the steps below to run the Start-up assistant:
- Use the MENU key to access the menu list.
- Select Assistants.
- Select Start-up Assistants.
- Follow the screen instructions to configure the system.
For common parameters and menu items, use the Help key to display descriptions. If you encounter alarms or faults, use the Help key or refer to the Diagnostic section of the User's manual.
