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.
•
Keep the drive in its package until you install it. After unpacking, protect the
drive from dust, debris and moisture.
•
Use the required personal protective equipment: safety shoes with metal toe
cap, safety glasses, protective gloves and long sleeves, etc.
•
When the drive or connected equipment is energized, do not do work on the
drive, motor cable, motor, control cables or control circuits.
•
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 power terminals.
Electrical safety precautions
1. Clearly identify the work location and equipment.
2. Disconnect all possible voltage sources. Make sure that re-connection is not
possible. Lock out and tag out.
•
Open the main disconnecting device of the drive.
•
If you have a permanent magnet motor connected to the drive,
disconnect the motor from the drive.
•
Disconnect any dangerous external voltages from the control circuits.
•
After you disconnect power from the drive, always wait 5 minutes to let
the intermediate circuit capacitors discharge before you continue.
3. Protect any other energized parts in the work location against contact.
4. Take special precautions when close to bare conductors.
5. Measure that the installation is de-energized.
•
Use a multimeter with a minimum impedance of 1 Mohm.
•
Make sure that the voltage between the drive input power terminals (U1,
V1, W1) and the ground (PE) is close to 0 V.
•
Make sure that the voltage between the drive output terminals (U2, V2,
W2) and the ground (PE) is close to 0 V.
•
Make sure that the voltage between the drive DC terminals (BRK+ and
BRK-) and the ground (PE) is close to 0 V.
6. Install temporary grounding as required by the local regulations.
7. Ask the person in control of the electrical installation work for a permit to
work.
See the drive user’s manual for the complete safety instructions.
1. Examine the installation area
The drive is intended for cabinet installation and has a degree of protection of
IP20 / UL open type as standard.
Make sure that in the installation area:
•
There is sufficient space above and below the drive for cooling, and hot air
does not recirculate. Refer to
Free space requirements
.
•
The ambient conditions are suitable. Refer to
Ambient conditions
.
•
The mounting surface is non-flammable and can hold the weight of the drive.
Refer to
Dimensions and weights
.
•
Materials near the drive are non-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.
2. Install the drive
You can install the drive with screws or to a DIN rail [Top Hat, W x H = 35 ×
7.5 mm (1.4 × 0.3 in)].
•
Make sure that there is a minimum of 75 mm (3 in) of free space above and
below the drive for cooling air.
•
When placing drives on top of each other in a panel or cabinet, make sure
that the hot air from the drives below do not directly enter the drive above.
WARNING!
Do not install the drive upside down. Make sure that the
cooling air exhaust (at the top) is above the cooling air inlet (at the
bottom).
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. Start to tighten the
screws into the
mounting holes.
4. Place the drive onto
the mounting screws.
5. Tighten the mounting
screws securely.
To install the
drive to a DIN
rail
1. Place the top of the
drive onto the DIN
installation rail in an
angle as shown in
figure.
2. Set the drive against
the wall.
3. To remove the drive,
press the release lever
on top of the drive.
3. Attach the clamping plates
1. Fasten the clamping
plate to the plate at
the bottom of the drive
with the provided
screws.
2. Frame sizes R0…R2:
Fasten the I/O
clamping plate to the
clamping plate with
the provided screws.
4. 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:
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 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.
5. Select the cables
Input power cable:
IEC/EN 61800-5-1 requires two protective earth (ground)
conductors. Prefer a symmetrical shielded cable (VFD cable).
Motor cable:
Use a symmetrical shielded cable (VFD cable) for the best EMC
performance and to meet the European EMC requirements.
Control cable:
Use a double-shielded twisted-pair cable for analog signals. Use a
double- or single-shielded cable for digital, relay and I/O signals. Do not mix 24 V
and 115/230 V signals in the same cable.
6. Connect the power cables
Connection diagram (shielded cables)
Connection procedure (shielded cables)
WARNING!
Make sure that the drive is compatible with the earthing
system. You can connect all drive types to a symmetrically grounded
TN-S system. For other systems, see the drive user’s manual.
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.
2. Strip the motor cable. Ground the cable shield
under the grounding clamp. Twist the motor
cable shield into a bundle, mark it accordingly
and connect it to the grounding terminal.
Connect the phase conductors to the U2, V2 and
W2 terminals.
3. If applicable, connect the brake resistor cable to
the BRK+ and BRK- terminals. Use a shielded
cable and ground the shield under the
grounding clamp.
4. Mechanically attach the cables on the outside of
the drive.
1 360-degree grounding of the cable shield. Required for the motor cable and brake
resistor cable, recommended for the input power cable.
2 Use a separate grounding cable if the conductivity of the cable shield is not sufficient
(smaller than the conductivity of the phase conductor) for the protective grounding, or
there is no symmetrically constructed grounding conductor in the cable.
3 In one-phase installations, connect phase to U1/L, neutral to V1/N and leave W1
disconnected.
4 Use two grounding conductors if the cross-section of a single grounding conductor is
less than 10 mm2 Cu or 16 mm2 AI (IEC/EN 61800-5-1). For example, use the cable shield
in addition to the fourth conductor.
5 Use a separate grounding cable (line side) if the conductivity of the fourth conductor or
shield is not sufficient for the protective grounding.

to the terminals.
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. Torque
the terminals to 0.4 N·m (3.5 lbf·in).
4. For double-shielded cables, twist
also the grounding conductors of
each pair in the cable together and
connect the bundle to the SCR
terminal (terminal 1).
5. Mechanically attach the control
cables on the outside of the drive.
6. If you are going to use an optional
Safe Torque Off function, connect
