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.
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:
•
Drive
•
Quick installation and start-up guide
•
A set of spare EMC screws
Make sure that there are no signs of damage to the items.
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
reforming instructions
(
3BFE64059629
[English]).
Select the cables and fuse
•
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).
3AXD50001017705
Size: Refer to ACS280 Hardware Manual (
•
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
power cable sizes
.
Examine the installation area
The drive has a degree of protection of IP00 / UL open type as standard and must be installed
into cabinet/enclosure.
Examine the site where you will install the drive. Make sure that:
•
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
•
The installation surface is 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.
•
The installation direction should obey the instruction in hardware manual.
(
3AXD50001017705
[English]).
Install the drive
WARNING! ACS280 drive may become damaged if operated without a suitable
heat-sink. Do not operate the drive without providing suitable heat-sink capacity
for the drive and application requirement.
•
ACS280 must be mounted onto a suitable flat metallic surface with sufficiently low
thermal resistance to allow dissipation of the heat produced. For detailed information,
Planning the cooling of the drive
please refer to the

1.
Make marks onto the surface for the mounting holes. Refer to
weights
.Download the mounting template on
library.abb.com
2.
Drill the holes for the mounting screws. If necessary, install suitable plugs or anchors into
the holes.
3.
Apply the thermal compound onto the cold-plate surface of the drive. About how to
properly apply the thermal compound, refer to ACS280 Hardware Manual
(
3AXD50001017705
[English]).
4. Put the drive onto the mounting holes.
5.
Tighten the mounting screws.
Measure the insulation resistance
Drive: Do not do voltage tolerance or insulation resistance tests on the drive, because this can
cause damage to the drive.
Input power cable: Before you connect the input power cable, measure the insulation of the
input power cable. 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 T1/U, T2/V and T3/W.
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
ohm
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.
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). The drive is delivered with the metal EMC and VAR screws installed. There are also spare
plastic EMC/VAR screw included in drive delivery. The table shows when to use the metal
EMC/VAR screw (connect the internal EMC filter) or plastic EMC/VAR screw(disconnect the
internal EMC filter).

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
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.
