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
4. Examine the installation area
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
•
The ambient conditions meet the requirements. Refer to
•
The installation surface is as close to vertical as possible and strong enough to support
the weight of the drive. Refer to
•
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]).
•
Install the frame R0 drives upright. The frame R0 drives do not have a fan.
•
You can install the frame R1...R4 drives tilted by up to 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
1. Make marks onto the surface for the
Download the mounting template
on
2. Drill the holes for the mounting screws. If
necessary, install suitable plugs or anchors
into the holes.
3. Install the mounting screws into the holes.
Leave a gap between the screw head and
installation surface.
4. Put the drive onto the mounting screws.
5. Tighten the mounting screws.
To install the drive to a DIN rail for frame sizes R3 and R4
1. Move the locking part to the left. If necessary, use a flat-head screwdriver.
2. Push and hold the locking button down.
3. Put the top tabs of the drive onto the top edge of the DIN rail.
4. Put the drive against the bottom edge of the DIN rail.
5. Release the locking button.
6. Move the locking part to the right.
7. Make sure that the drive is correctly installed.
To remove the drive, open the locking part and lift the drive from the DIN rail.
6. 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.
7. 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 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 metal VAR screw (disconnect the varistor
circuit).
8. Connect the power cables
Connection diagram
(shielded cables)
1.
Disconnecting device.
2.
Two protective earth (ground) conductors. Drive safety standard IEC/EN61800-5-1
requires two PE conductors, if the cross-sectional area of the PE conductor is less than
10 mm
2
Cu or 16 mm
2
Al. For example, you can use the cable shield in addition to the
fourth conductor.
3.
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.
4.
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.
5.
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.
6.
Brake resistor and resistor cable (optional, for frame R2...R4 only).
Connection procedure
(shielded cables)
For the tightening torques, refer to
Terminal data for the power cables
.
