ABB ACS355 Series - DC Drive Quick Installation And Start-up Guide

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
• Materials near the drive are non-flammable.
• There are no sources of strong magnetic fields, such as high-current singlecore 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, 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.

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.
   

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.
   

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.
   

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.

Connect the power cables

Connection diagram (shielded cables)

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.

Connection procedure (shielded cables)

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.
   

Connect the control cables

Default I/O connections

The diagram shows the I/O connections when parameter9902 has value 1 (ABB STANDARD).

1. AI1 is used as a speed reference if vector mode is selected.
2. See parameter group 12 CONSTANT SPEEDS:

3. 0 = ramp times according to parameters 2202 and 2203. 1 = ramp times according to parameters 2205 and 2206.
4. 360 degree grounding under a clamp.

Tightening torque: 0.4 N·m / 3.5 lbf·in.

Connection procedure

To prevent inductive coupling, keep the signal wire pairs twisted all the way up 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 STO conductors to the correct terminals. Use a tightening torque of 0.4 N·m (3.5 lbf·in).
7. Unless you need to install the optional fieldbus module, slide the terminal cover back into place.
   

Install the fieldbus module (optional)

Install the control panel (if any)
