Safety

Use of warnings and notes

There are two types of safety instructions throughout this manual:

• Notes draw attention to a particular condition or fact, or give information on a
subject.

• Warnings caution you about conditions which can result in serious injury or death
and/or damage to the equipment. They also tell you how to avoid the danger . The
warning symbols are used as follows:

Electricity warning warns of hazards from electricity which can cause physical
injury and/or damage to the equipment.

General warning warns about conditions, other than those caused by electricity,
which can result in physical injury and/or damage to the equipment.

WARNING! The ACQ550 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, depending on the frame
size, UDC+ and UDC-, or 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 switched off from the input terminals of the
ACQ550, there may be dangerous voltage (from external sources) on the terminals
of the relay outputs RO1…RO3.

WARNING! When the control terminals of two or more drives 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 drives or an external supply.

Safety

6 ACQ550-U1 User’s Manual

WARNING! Disconnect the internal EMC filter when installing the drive on an IT
system (an ungrounded power system or a high-resistance-grounded [over 30 ohm]
power system), otherwise the system will be connected to ground potential through
the EMC filter capacitors. This may cause danger, or damage the drive.

Disconnect the internal EMC filter when installing the drive on a corner grounded TN
system, otherwise the drive will be damaged.

Note: When the internal EMC filter is disconnected, the drive is not EMC comp atible.
See section Disconnecting the internal EMC filter on page 23. Also see sections IT

systems on page 276 and Corner grounded TN systems on page 275.

WARNING! Do not attempt to install or remove EM1, EM3, F1 or F2 screws while
power is applied to the drive’s input terminals.

WARNING! Do not control the motor with the disconnecting device (disconnecting
means); instead, use the control panel start and stop keys and , or
commands via the I/O board of the drive. The maximum allowed number of charging
cycles of the DC capacitors (i.e. power-ups by applying power) is five in ten minutes.

WARNING! The ACQ550-U1 is not field repairable. Never attempt to repair a
malfunctioning drive; contact the factory or your local Authorized Service Center for
replacement.

WARNING! The ACQ550 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 chapter Technical

data on page 267.

Note: For more technical information, contact the factory or your local ABB
representative.

Note: Frame sizes R3 and R4 have four holes along the top. Use only two. If
possible, use the two outside holes (to allow room to remove the fan for
maintenance).

Note: ACS400 drives can be replaced using the original mounting holes. For R1 and
R2 frame sizes, the mounting holes are identical. For R3 and R4 frame sizes, the
inside mounting holes on the top of ACQ550 drives match ACS400 mounts.

Disconnecting the internal EMC filter

On certain types of systems, you must disconnect the internal EMC filter, otherwise
the system will be connected to ground potential through the EMC filter capacitors,
which might cause danger, or damage the drive.

Note: When the internal EMC filter is disconnected, the drive is not EMC compa tible.
The following table shows the installation rules for the EMC filter screws in order to

connect or disconnect the filter, depending on the system type and the frame size.
For more information on the different system types, see IT sy stems on page 276 and

WARNING! All ELV (Extra Low V oltage) circuits connected to the drive must be used
within a zone of equipotential bonding, i.e. within a zone where all simultaneously
accessible conductive parts are electrically connected to prevent hazardous voltages
appearing between them. This is accomplished by a proper factory grounding.

The terminals on the control board as well as on the optional modules attachable to
the board fulfil the Protective Extra Low Voltage (PELV) requirements stated in
EN 50178, provided that the external circuits connected to the terminals also fulfil
the requirements and the installation site is below 2000 m (6562 ft).

You can wire the digital input terminals in either a PNP or NPN configuration.

Checking motor and motor cable insulation

WARNING! Check the motor and motor cable insulation before connecting the drive
to input power. For this test, make sure that motor cables are NOT connected to the
drive.

1. Complete motor cable connections to the motor, but NOT to the drive output
terminals (U2, V2, W2).

2. Measure the insulation resistance between each
phase conductor and the Protective Earth conductor
using a measuring voltage of 500 V DC. The
insulation resistance of an ABB motor must exceed
10 Mohm (reference value at 25 °C or 77 °F). For the
insulation resistance of other motors, please consult
the manufacturer’s instructions. Note: Moisture inside the motor casing will reduce
the insulation resistance. If moisture is suspected, dry the motor and repeat the
measurement.
