Safety
Warning! The ACH550 adjustable speed AC drive should ONLY be installed by
a qualified electrician.
Warning! Even when the motor is stopped, dangerous voltage is present at the
Power Circuit terminals U1, V1, W1 and U2, V2, W2 and, where present, UDC+,
UDC-, BRK+ and BRK-.
Warning! Dangerous voltage is present when input power is connected. After
disconnecting the supply, wait at least 5 minutes (to let the intermediate circuit
capacitors discharge) before removing the cover.
Warning! Even when power is removed from the input terminals of the
ACH550, there may be dangerous voltage (from external sources) on the
terminals of the relay outputs R01…R03.
Warning! When the control terminals of two or more drive units are connected
in parallel, the auxiliary voltage for these control connections must be taken
from a single source which can either be one of the units or an external
supply.
Warning! The ACH550-UH is not a field repairable unit. Never attempt to repair
a malfunctioning unit; contact the factory or your local Authorized Service
Center for replacement.
Warning! The ACH550 will start up automatically after an input voltage
interruption if the external run command is on.
Warning! The heat sink may reach a high temperature. See "Technical Data" on
page 225.
Warning! If the drive will be used in a floating network, remove screws at EM1
and EM3 (Frame size R1…R4), or F1 and F2 (Frame size R5 or R6). See
diagrams on page 14 and page 15 respectively.
Note! For more technical information, contact the factory or your local ABB sales
representative.

Wiring Overview
Warning! Ensure the motor is compatible for use with the ACH550. The
ACH550 must be installed by a competent person in accordance with the
considerations defined in "Preparing for Installation" on page 8. If in doubt,
contact your local ABB sales or service office.
As you install the wiring, observe the following:
• There are two sets of wiring instructions – one set for each enclosure type (IP 21
/ UL type and IP 54 / UL type 12). Be sure to select the appropriate procedure.
• For the power connection points on the drive see the "Connection Diagrams"
section below.
• Use separate conduit runs to keep these three classes of wiring apart:
– Input power wiring.
– Motor wiring.
– Control/communications wiring.
• For details on power connections, refer to the following sections in "Technical
Data":
–"Input Power Connections" on page 228.
–"Motor Connections" on page 232.
• For floating networks (also known as IT, ungrounded, or high impedance
networks):
– Disconnect the internal RFI filter by removing both the EM1 and EM3 screws
(frame sizes R1…R4, see page 14), or F1 and F2 screws (frame sizes
R5…R6, see page 15).
– Do NOT install an external filter, such as one of the kits listed in the filter table
on 236. Using an EMC/RFI filter grounds the input power through the filter
capacitors, which could be dangerous and could damage the unit.
– Where EMC requirements exist, check for excessive emission propagated to
neighboring low voltage networks. In some cases, the natural suppression in
transformers and cables is sufficient. If in doubt, use a supply transformer with
static screening between the primary and secondary windings.
• For details on control connections, refer to the following sections:
–"Control Connections" on page 237.
–"Application Macros" starting on page 35.
• For electro-magnetic compliance (EMC), follow local codes and the requirements
in "Motor Cable Requirements for CE & C-Tick Compliance" on page 234. For
example:
– Properly ground the wire screen cable shields.
– Keep individual un-screened wires between the cable clamps and the screw
terminals as short as possible.
– Route control cables away from power cables.

Installation
Start-Up
The ACH550 has default parameter settings that are sufficient for many situations.
However, review the following situations. Perform the associated procedures as
appropriate.
Spin Motor
When first installed and started the control panel displays a welcome screen with the
following options.
• Press Exit to commission the drive as described in section “Start-Up by Changing
the Parameters Individually” on page 23.
• Press Enter to move to the following options:
– Select “Commission Drive” to commission the drive as described in section
“Start-Up by Using the Start-Up Assistant” on page 23.
– Select “Spin Motor” to operate the motor prior to commissioning. This option
operates the motor without any commissioning, except entry of the motor data
as described below. Spin Motor is useful, for example, to operate ventilation
fans prior to commissioning.
Note! When using Spin Motor, the motor speed is limited to the range 1/3…2/3 of
maximum speed. Also, no interlocks are activated. Finally, once the drive is
commissioned, the welcome screen and this option no longer appear.
Motor Data
The motor data on the ratings plate may differ from the defaults in the ACH550. The
drive provides more precise control and better thermal protection if you enter the
rating plate data.
1. Gather the following from the motor ratings plate:
•Voltage
• Nominal motor current
• Nominal frequency
• Nominal speed
• Nominal power
2. Edit parameters 9905…9909 to the correct values.
• Assistant Control Panel: The Start-up Assistant walks you through this data entry
(see page 27).
• Basic Control Panel: Refer to "Parameters Mode" on page 26, for parameter
editing instructions.
Macros
Note! Selecting the appropriate macro should be part of the original system design,
since the control wiring installed depends on the macro used.
