ABB MICRO DRIVES
Quick installation and start-up guide
WARNING! Obey these instructions. If you ignore them, injury or death,
or damage to the equipment can occur. If you are not a qualified
electrical professional, do not do electrical installation or maintenance
Do not do work on the drive, motor cable, motor, or control cables when the
drive is connected to the input power. Before you start the work, isolate the
drive from all dangerous voltage sources and make sure that it is safe to
start the work. Always wait for 5 minutes after disconnecting the input
power to let the intermediate circuit capacitors discharge.
Do not do work on the drive when a rotating permanent magnet motor is
connected to it. A rotating permanent magnet motor energizes the drive,
including its input and output terminals.
1. Unpack the delivery
Keep the drive in its package until you are ready to install it. After unpacking,
protect the drive from dust, debris and moisture. Make sure that these items are

quick installation and start-up guide.
Make sure that there are no signs of damage to the items.
2. Reform the capacitors
If the drive has not been powered up for a year or more, you must reform the DC
link capacitors. The manufacturing date is on the type designation label. Refer
Guide for capacitor reforming
3. Select the cables and fuses
Select the power cables. Obey the local regulations.
Input power cable: ABB recommends to use symmetrical shielded cable
(VFD cable) for the best EMC performance.
Motor cable: Use symmetrical shielded cable (VFD cable) for the best
EMC performance. Symmetrical shielded cable also reduces bearing
currents, wear, and stress on motor insulation.
Power cable types: In IEC installations, use copper or aluminum cables (if
permitted). In UL installations, use only copper cables.
Current rating: max. load current.
Voltage rating: min. 600 V AC.
Temperature rating: In IEC installations, select a cable rated for at least
70 °C (158 °F) maximum permissible temperature of conductor in
continuous use. In UL installations, select a cable rated for at least 75 °C
Size: Refer to
Fuses and typical power cable sizes
sizes and to
Terminal data for the power cables
Select the control cables. Use double-shielded twisted-pair cable for analog
signals. Use double-shielded or single-shielded cable for the digital, relay and
I/O signals. Do not run 24 V and 115/230 V signals in the same cable.
Protect the drive and input power cable with the correct fuses. Refer to
Fuses and typical power cable sizes
4. Examine the installation site
The drive is intended for cabinet installation and has a degree of protection of
IP20 / UL open type as standard.
Examine the site where you will install the drive. Make sure that:
The installation site is sufficiently ventilated and hot air does not recirculate.
There is sufficient free space around the drive for cooling, maintenance, and
operation. For the minimum free space requirements, refer to
The ambient conditions meet the requirements. Refer to
The installation surface is as close to vertical as possible and strong enough
Dimensions and weights
to support the weight of the drive. Refer to
The installation surface, floor and materials near the drive are not flammable.
There are no sources of strong magnetic fields, such as high-current single-
core conductors or contactor coils near the drive. A strong magnetic field
can cause interference or inaccuracy in the operation of the drive.
5. Install the drive
You can install the drive with screws, or to a DIN rail (top hat type, width × height
= 35 mm × 7.5 mm [1.4 in × 0.3 in]).
Do not install the drive upside down. Make sure that the cooling air exhaust is
above the cooling air inlet.
To install the drive with screws
1. Cut out the mounting
template from the
package and use it to
mark the locations for
the mounting holes.
2. Make the holes for the
mounting screws and
install suitable plugs or
3. Install the mounting
screws. Leave a gap
between the screw

To install the drive to a DIN rail
1. Put the top of the drive
onto the DIN

angle as shown in the
2. Put the drive against
3. Make sure that the drive
is correctly installed.
4. To remove the drive,
press the release lever on top of the drive.
6. Attach the clamping plates
1. Attach the clamping
plate to the plate at the
bottom of the drive
with the provided
2. Attach the I/O clamping
plate to the clamping
plate with the provided
7. Measure the insulation resistance
Measuring the insulation is typically not required in North America.
Drive: Do not do voltage tolerance or insulation resistance tests on the drive,
because this can cause damage to the drive.
Input power cable: Measure the insulation of the input power cable before you
connect it to the drive. Obey the local regulations.
Motor and motor cable:
1. Make sure that the motor cable is connected to the motor and disconnected
from the drive output terminals U2, V2 and W2.
2. Use a voltage of 1000 V DC to measure the
insulation resistance between each phase
conductor and the protective earth conductor.
The insulation resistance of an ABB motor must
be more than 100 Mohm (at 25 °C/77 °F). For the
insulation resistance of other motors, refer to
the manufacturer's documentation. Moisture in
the motor decreases the insulation resistance.
If you think that there is moisture in the motor,
dry the motor and do the measurement again.
8. Make sure that the drive is compatible with the
You can connect all drive types to a symmetrically grounded TN-S system
Before you connect the drive to a corner-grounded delta system or IT system
(ungrounded or high-resistance grounded), remove the metal EMC filter
grounding screw. If the drive has a plastic EMC screw (drives with type code
ACS150-03U-...), it is not necessary to remove the screw.
9. Connect the power cables

3. Use a separate grounding cable for the motor side, if the conductivity of the
shield is not sufficient, or if there is no symmetrically constructed PE
conductor in the cable.
4. 360-degree grounding of the cable shield is required for the motor cable and
