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:
•
Drives (Quantity of drives per package varies on different package type)
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).
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.
Size: Refer to ACS280-04LC Hardware manual (3AXD50001176129[English]).
•
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
typical power cable sizes
.
Examine the installation area
The drive has a degree of protection of IP20 as standard and must be installed into cabinet/
enclosure.
Examine the site where you will install the drive. Make sure that:
•
The ambient conditions of the drive meet the specifications. See the technical data.
•
The material behind, above and below the drive is non-flammable.
•
There is sufficient free space around the drive for cooling, maintenance, and operation.
See the free space specifications for the drive.
•
Make sure that 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.
Install the drive
ACS280-04LC must be installed onto a suitable flat metallic surface.
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. Put the drive onto the mounting holes.
4. 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 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).

not meet the requirements for the PE conductor.
6. Motor cable. Note: ABB recommends to use a symmetrical shielded cable (VFD cable) as
the motor cable.
7. Separate PE cable (motor side). 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.
8. 360-degree grounding of the cable shield. Required for the motor cable and brake
resistor cable, recommended for the input power cable.

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.
7
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.
