ABB ACS355 series Installation manual

Safety instructions
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
work.
• 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
included:
• clamping plates, clamps and screws
• fieldbus option ground plate
• panel cover
• mounting template, integrated into the package
• quick installation and start-up guide
• possible options (extension modules, control panels).
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
to
Guide for capacitor reforming (3AFE68735190 [English]).
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
(167°F).
•Size: Refer to Fuses and typical power cable sizes for the typical cable
sizes and to
Terminal data for the power cables for the maximum cable
sizes.
• 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
Free space
requirements
.
• The ambient conditions meet the requirements. Refer to Ambient
conditions
.
• The installation surface is as close to vertical as possible and strong enough
to support the weight of the drive. Refer to
Dimensions and weights .
• 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.

Quick installation and start-up guide
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
anchors.
3. Install the mounting
screws. Leave a gap
between the screw
head and mounting
surface.
4. Place the drive onto the
mounting screws.
5. Tighten the mounting
screws.
To install the drive to a DIN rail
1. Put the top of the drive
onto the DIN
installation rail at an
angle as shown in the
figure.
2. Put the drive against
the wall.
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
screws.
2. Frame sizes R0…R2:
Attach the I/O clamping
plate to the clamping
plate with the provided
screws.
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
grounding system
You can connect all drive types to a symmetrically grounded TN-S system
(center-grounded wye).
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
ACS355-03U-…), it is not necessary to remove the screw.
9. Connect the power cables
Connection diagram (shielded cables)
1. Two protective earth (ground) conductors. Drive safety standard IEC/EN/
UL 61800-5-1 requires two PE conductors, if the cross-sectional area of the
PE conductor is less than 10 mm2Cu or 16 mm2Al. For example, you can use
the cable shield in addition to the fourth conductor.
2. Use a separate grounding cable or a cable with a separate PE conductor for
the line side, if the conductivity of the fourth conductor or shield does not
meet the requirements for the PE conductor.
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
brake resistor cable (if used). It is also recommended for the input power
cable.
5. 1-phase drives: Connect phase to U1 and neutral to V1. Keep W1
disconnected.
Connection procedure (shielded cables)
For the tightening torques, refer to Terminal data for the power cables .
1. Strip the input
power cable. Ground
the cable shield (if
any) under the
grounding clamp.
Twist the cable
shield into a bundle,
mark it accordingly
and connect it to the
grounding terminal.
Connect other
grounding
conductors (PE) to the grounding terminal. Connect the phase conductors to
the U1, V1 and W1 terminals.

Do the connections according to the default control connections of the
application macro that you select.
Default I/O connections (ABB standard macro)
The diagram shows the I/O connections when parameter 9902 is set to 1
(ABB STANDARD).
Connection procedure
To prevent inductive coupling, keep the
signal wire pairs twisted all the way up
to the terminals. The tightening torque
for the terminal connections is 0.4 N·m
(3.5 lbf·in).
1. Remove the terminal cover.
2. Strip the outer insulation of the
cable and ground the bare shield
360 degrees under the clamp.
3. Connect the conductors to the
correct control terminals.

Safe torque off (STO)
The drive has a Safe torque off function (STO) in accordance with IEC/EN
61800-5-2. It can be used, for example, as the final actuator device of safety
circuits that stop the drive in case of danger (such as an emergency stop
circuit).
When activated, the STO function disables the control voltage of the power
semiconductors of the drive output stage, thus preventing the drive from
generating the torque required to rotate the motor. The control program
generates an indication as defined by parameter
3025. If the motor is running
when Safe torque off is activated, it coasts to a stop. Closing the activation
switch deactivates the STO. Any faults generated must be reset before
restarting.
The STO function has a redundant architecture, that is, both channels must be
used in the safety function implementation. The safety data given is calculated
for redundant use, and does not apply if both channels are not used.
WARNING! The STO function does not disconnect the voltage from the
main and auxiliary circuits of the drive.
Notes:
•If stopping by coasting is not acceptable, stop the drive and machinery
using the appropriate stop mode before activating the STO.
•The STO function overrides all other functions of the drive.
Wiring
The safety contacts must open/close within 200 ms of each other.
Double-shielded twisted-pair cable is recommended for the connection. The
maximum length of the cabling between the switch and the drive control unit is
300 m (1000 ft). Ground the shield of the cable at the control unit only.
Validation
To ensure the safe operation of a safety function, a validation test is required.
The test must be carried out by a competent person with adequate expertise
and knowledge of the safety function. The test procedures and report must be
documented and signed by this person. Validation instructions of the STO
function can be found in the drive hardware manual.
Technical data
•Minimum voltage at IN1 and IN2 to be interpreted as “1”: 13 V DC
•STO reaction time (shortest detectable break): 10 microseconds
•STO response time: 2 ms (typical), 5 ms (maximum)
•Fault detection time: Channels in different states for longer than 200 ms
•Fault reaction time: Fault detection time + 10 ms
•STO fault indication (parameter 3025 ) delay: < 200 ms
•STO warning indication (parameter 3025 ) delay: < 200 ms
•Safety integrity level (EN 62061): SIL 3
•Performance level (EN ISO 13849-1): PL e
The drive STO is a type A safety component as defined in IEC 61508-2.
For the full safety data, exact failure rates and failure modes of the STO
function, refer to the drive hardware manual.
