Safety instructionsRead the safety instructions in theACQ80-04 drives (0.75 to 22 kW) Hardwaremanual (3AXD50000170661[EN]).WARNING! Obey these safety instructions to prevent physical injury ordeath, or damage to the equipment. If you are not a qualified electrician,do not do electrical installation or maintenance work.• Keep the drive in its package until you install it. After unpacking, protect thedrive from dust, debris and moisture.• Use the required personal protective equipment: safety shoes with metal toecap, safety glasses, protective gloves, etc.• Disconnect all possible voltage sources. Lock and tag.• When the drive or connected equipment is energized, do not do work on thedrive, motor cable, motor, control cables or control circuits.• After you disconnect the input AC and DC (PV) power, wait for five minutes tolet the DC bus capacitors discharge. Measure and make sure that the,• voltage between the DC bus terminals (UDC+, UDC-) is 0 V.• DC voltage between the DC bus terminals (UDC+, UDC-) andground (PE) is 0 V.• Make sure that the equipment is not energized. Use a multimeter with animpedance of at least 1 Mohm. Make sure that the,• voltage between the drive input power terminals (L1, L2, L3) and theground (PE) is 0 V.• phase to phase voltage between the drive input power terminals (L1, L2,L3) is 0 V.• voltage between the drive output terminals (T1/U, T2/V, T3/W) and theground (PE) is 0 V.• phase to phase voltage between drive output terminals (T1/U, T2/V, T3/W) is 0 V AC.• If you use a permanent magnet synchronous motor, do not do work on thedrive when the motor rotates. A permanent magnet motor that rotatesenergizes the drive and the output power terminals.WARNING! The installation, start-up and operation of this equipmentrequires detailed instructions. Refer to the detailed instructions in theACQ80 Hardware manual (3AXD50000170661 [EN]) andACQ80Firmware manual (3AXD50000170654 [EN]). You can download thesemanuals from the ABB website.1. Examine the installation areaThe drive is intended for cabinet installation and has a degree of protection ofIP20 / UL open type.Make sure that in the installation area:• There is sufficient cooling and hot air does not recirculate back to air inlet ofthe drive.• There is sufficient space above and below the drive for cooling. Refer toFreespace requirements.• The ambient conditions are suitable. Refer toAmbient conditions.• The mounting surface is non-flammable and can hold the weight of the drive.Refer toDimensions and weights.• Materials near the drive are non-flammable.2. Install the driveYou can install the drive with screws or to a DIN rail [Top Hat, W x H = 35 x 7.5 mm(1.4 x 0.3 in)].Installation requirements:• Make sure that there is a minimum of 75 mm (2.9 in) of free space at the topand bottom of the drive for cooling air.• You can install several drives side by side. Side-mounted options requireapproximately 20 mm (0.8 in) of space on the right side of the drive.WARNING! Do not install the drive upside down. Make sure that thecooling air exhaust (at the top) is always above the cooling air inlet (atthe bottom). To install the drive with screws1. Make marks onto the surface for the mountingholes. Refer toDimensions and weights. The R2and R3 drives come with a mounting template.2. Make the holes for the mounting screws andinstall suitable plugs or anchors if required.3. Start to tighten the screws into the mountingholes.4. Install the drive onto the mounting screws.5. Tighten the mounting screws. To install the drive on a DIN rail1. Move the locking part to the left.2. Push and hold the locking buttondown.3. Put the top tabs of the drive onto thetop edge of the DIN installation rail.4. Put the drive against the bottom edgeof the DIN installation rail.5. Release the locking button.6. Move the locking part to the right.7. Make sure that the drive is correctlyinstalled.8. To remove the drive, use a flat-headscrewdriver to open the locking part.3. Measure the insulation resistanceDrive: 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 theinsulation 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 disconnectedfrom the drive output terminals T1/U, T2/V and T3/W.2. Use a voltage of 1000 V DC tomeasure the insulationresistance between eachphase conductor and theprotective earth conductor.The insulation resistance ofan ABB motor must be morethan 100 Mohm (at 25 °C/77 °F). For the insulationresistance of other motors, refer to the manufacturer’s documentation.Moisture in the motor decreases the insulation resistance. If you think thatthere is moisture in the motor, dry the motor and do the measurementagain.4. Select the cablesSee the drive hardware manual for the cable selection instructions.Note:Input power cable: IEC/EN 61800-5-1 requires two protective earth (ground)conductors.Motor cable: ABB recommends to use symmetrical shielded cable (VFD cable)for the best EMC performance.Control cable: Use a double-shielded twisted-pair cable for the analog signals.Use a double- or single-shielded cable for the digital, relay and I/O signals. Donot mix 24 V and 115/230 V signals in the same cable.5. Connect the power cables Connection diagram (shielded cables)CAUTION! ABB recommends to use a lightning pole to avoid lightningstrike to the drive. Make sure that the lightening pole ground is notcommon for PV cell, drive, and motor.If you do wiring in conduits, see the drive hardware manual for moreinformation.1. Reverse polarity diodes.2. EMI filter is optional but is mandatory for IEC/EN62920 standardcompliance which is required in Europe.3. Ground connection should be common for MOV, drive, and pump.Note: ACQ80 is intended to be used for speed control of 3ph AC pump motorsand is powered from either AC Grid or DC photo-voltaic array. ABB recommendsnot to use it as an island grid forming inverter or to supply generic 1ph or 3phloads, other than 3ph AC pump motors. Connection procedure (shielded cables)If you do wiring in conduits, see the drive hardware manual for moreinformation.WARNING! Obey the safety instructions in theACQ80 Hardwaremanual (3AXD50000170661 [EN]). If you ignore them, injury or death, ordamage to the equipment can occur.WARNING! Make sure that the drive is compatible with the powersupply system. You can connect all drive types to a symmetricallygrounded TN-S system.
