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 Capacitor reforming instructions (3BFE64059629 [English]).

Select the cables and fuses

Select the power cables. Obey the local regulations.
• Input power cable: ABB recommends using asymmetrical shielded cable (VFD cable) for the best EMC performance.
• Motor cable: Use symmetrical shielded cable (VFD cable) for the best EMC performance. The 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 the 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.

Examine the installation area

The drive is intended for cabinet installation and has a degree of protection of IP20 / UL open type.
Examine the site where you will install the driver. 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 in the operation of the drive.

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]).

Install R0 drives vertically. R0 drives do not have a cooling fan.
You can install drives with frame size R1…R4 tilted by a maximum of 90 degrees, from vertical to fully horizontal orientation.
Do not install the drive upside down.
You can install several drives side by side.

To install the drive with screws

Make marks on the surface for the mounting holes. Refer to Dimensions and weights. Use the included mounting template for frames R3 and R4.
Drill the holes for the mounting screws. If necessary, install suitable plugs or anchors into the holes.
Install the mounting screws into the holes. Leave a gap between the screw head and the installation surface.
Put the drive onto the mounting screws.
Tighten the mounting screws.

To install the drive to a DIN rail

Move the locking part to the left. If necessary, use a flat-head screwdriver.
Push and hold the locking button down.
Put the top tabs of the drive onto the top edge of the DIN rail.
Put the drive against the bottom edge of the DIN rail.
Release the locking button.
Move the locking part to the right.
Make sure that the drive is correctly installed.

To remove the drive, open the locking part and lift the drive from the DIN rail.

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:

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.
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 an asymmetrically grounded TN-S system (center-grounded wye). The drive is delivered with the EMC and VAR screws installed. The material of the screws (plastic or metal) depends on the product variant. The table shows when to remove the metal EMC screw (disconnect the internal EMC filter) or the metal VAR screw (disconnect the varistor circuit).

Screw label	Factory default screw material	Grounding systems
Screw label	Factory default screw material	Symmetrically grounded TN-S systems (center-grounded wye)	Corner-grounded delta, midpoint grounded delta and TT systems	IT systems (ungrounded or high-resistance grounded)
EMC	Metal	Do not remove	Remove	Remove
EMC	Plastic 1)	Do not remove 2)	Do not remove	Do not remove
VAR	Metal	Do not remove	Do not remove	Remove
VAR	Plastic	Do not remove	Do not remove	Do not remove

UL (NEC) types have a plastic EMC screw.
Can install the metal screw (included in the drive delivery) to connect the internal EMC filter.

Connect the power cables

Connection diagram (shielded cables)

Disconnecting device
Two protective earth (ground) conductors. Drive safety standard IEC/EN 61800-5-1 requires two PE conductors if the cross-sectional area of the PE conductor is less than 10 mm Al. For example, you can use the cable shield in addition to the fourth conductor. Cu or 16 mm
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.
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.
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.
Brake resistor and resistor cable (optional).

Connection procedure (shielded cables)
For the tightening torques, refer to Terminal data for the power cables.

Loosen the screw on the front cover. Then lift the front cover-up.
Attach the residual voltage warning sticker in the local language to the drive.
Strip the motor cable.
Ground the motor cable shield under the grounding clamp.
Twist the motor cable shield into a bundle, mark it and connect it to the grounding terminal.
Connect the phase conductors of the motor cable to terminals T1/U, T2/V and T3/W.
If used, connect the brake resistor cable to terminals R- and UDC+. Use a shielded cable and ground the shield under the grounding clamp.
Make sure that the R- and UDC+ terminal screws are tightened. Do this step also if you do not connect cables to the terminals.
Strip the input power cable.
If the input power cable has a shield, ground the shield under the grounding clamp. Then twist the shield into a bundle, mark it and connect it to the grounding terminal.
Connect the PE conductor of the input power cable to the grounding terminal. If necessary, use a second PE conductor.
In 3-phase drives, connect the phase conductors of the input power cable to terminals L1, L2 and L3. In 1-phase drives, connect the phase and neutral conductors to terminals L1 and L2.
Mechanically attach the cables on the outside of the drive.

Install the communication module

To install the communication module (I/O module or Fieldbus module):

Pull out the locking tab of the communication module.
Align the communication module contacts with the contacts on the drive.
Carefully push the module into position.
Push in the locking tab of the communication module.
Tighten the locking screw to fully attach and electrically ground the communication module.

Connect the control cables

Do the connections according to the application macro that you select. The ABB standard macro is the default macro. Keep the signal wire pairs twisted as near to the terminals as possible to prevent inductive coupling. The tightening torque for the terminal connections is 0.5 … 0.6 N·m (4.4 … 5.3 lbf·in).

Strip a part of the outer shield of the control cable for grounding.
Use a cable tie to ground the outer shield to the grounding tab.
Strip the control cable conductors.
Connect the conductors to the correct control terminals.
Connect the shields of the twisted pairs and grounding wires to the SCR terminal.
Mechanically attach the control cables on the outside of the drive.

Default I/O connections (ABB standard macro) 1) × = on base unit, empty = on RIIO-01 I/O extension module

Embedded Fieldbus connection
You can connect the drive to an EIA-485 serial communication link through the embedded Fieldbus interface on the RIIO-01 module. The embedded Fieldbus interface supports the Modbus RTU protocol.
To configure Modbus RTU communication with the embedded Fieldbus:

Connect the Fieldbus cables and the necessary I/O signals.
Use the termination switch to set the correct termination settings.
Power up the drive and set the necessary parameters.

A connection example is shown below.

The devices at the ends of the Fieldbus must have the termination set to ON. All other devices must have the termination set to OFF (1).
Attach the cable shields together at each drive, but do not connect them to the drive.
Connect the shields only to the grounding terminal in the automation controller.
Connect the signal ground (DGND) conductor to the signal ground reference terminal in the automation controller. If the automation controller does not have a signal ground reference terminal, you can connect the signal ground to the cable shields through a 100-ohm resistor, preferably near the controller.

Install the control panel

To install the control panel:

Close the front cover and tighten the screw.
Put the bottom edge of the control panel into position.
Push the top of the control panel until it locks into position.

Startup the drive

WARNING! Before you start up the drive, make sure that the installation is completed. Make sure also that it is safe to start the motor.
Disconnect the motor from other machinery, if there is a risk of damage or injury.

The control panel has softkeys below the display to access the related commands, and arrow keys to navigate the menu and change parameter values.
Push the “?” button to open the help function.
Make sure that you have the motor nameplate data available.

The recommended branch protection fuses must be used to maintain the IEC/EN/UL 61800-5-1 listing.
The drive is suitable for use on a circuit capable of delivering not more than 100000 symmetrical amperes (RMS) at 480 V (480 V drive types) or 240 V (240 V drive types) maximum when protected by the fuses given in this table.
As an alternative to Class T fuses, you can use Class J or Class CF fuses of the same voltage and current rating for branch circuit protection of 3-phase drives.

A side-mounted option requires approximately 20 mm (0.8 in) of space on the right side of the drive.

Markings
The applicable markings are shown on the type designation label of the drive.

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 31.22. 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.
A 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.
