• DO NOT touch unshielded components or terminal strip screw connections with voltage present.

• DO NOT short across terminals PA/+ and PC/– or across the DC bus capacitors.

• Before servicing the drive:

- Disconnect all power.

- Place a “DO NOT TURN ON” label on all power disconnects.

- Lock all power disconnects in the open position.

- Disconnect all power, including external control po wer that may be present, bef ore servicing the drive. WAIT 15 MINUTES to al low

the DC bus capacitors to discharge. Then follow the “Bus Voltage Measurement Procedure” on page 25 to verify that the DC voltage is less than 45 V. The drive LED is not an indicator of the absence of DC bus voltage.

• Install and close all covers before applying power or starting and stopping the drive.

Failure to follow these instructions will result in death or serious injury.

DANGER

UNINTENDED EQUIPMENT OPERATION

Before turning on the drive or upon exitin g the configuratio n menus, ensure t hat the inputs a ssigned to t he Run command are in a state that will not cause the drive to run. Otherwise, the motor can start immediately.

Failure to follow these instructions will result in death, serious injury, or equipment damage.

WARNING

LOSS OF CONTROL

• The designer of any control scheme must consider the potential failure modes of control paths and, for certain critical con trol functions, provide a means to achieve a safe state du ring and after a path failure. Examples of critical control functions are emergency stop and overtravel stop.

• Separate or redundant control paths must be provided for critical control functions.

• System control paths may include communication links. Considerat ion must be given to the implications of unanticipate d transmission delays or failures of the link (1).

• Each implementation of an Altivar 21 drive must be individually and thoroughly tested for proper operation before being placed into service.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

(1)For additional information refer to NEMA ICS 1.1 (latest edi tion), “Safety Guidel ines for the Application, In stallation, and Maintenance of

Solid State Control” and to NEMA ICS 7.1 (latest edition), “Safety Standards for Construction and Guide for Selection, Installation and Operation of Adjustable-Speed Drive Systems.”

Wiring

Wiring recommendations

Good wiring practice requires the separation of co ntrol c ircuit wiri ng from a ll po wer (li ne) wiring . In additio n, power wi ring to the motor must have the maximum possible separation from all other power wiring, whether from the same drive or other drives. Do not run power and control wiring , or multiple power wirin g, in the same conduit. Th is separation reduces the possibility of coupling electrical transients from power circuits into control circuits or from motor power wiring into other power circuits.

WARNING

IMPROPER WIRING PRACTICES

• Follow the wiring practices described in this document in addition to those al ready required by the National Electri cal Code and local electrical codes.

• Do not apply input line voltage to the output terminals (U/T1, V/T2, W/T3).

• Check the power connections before energizing the drive.

• If replacing another drive, verify that all wiring connections to the ATV21 drive comply with all wiring instructions in this manual.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

Follow the practices below when wiring ATV21 drives:

• Verify that the voltage and frequency of the input suppl y line and the voltage, freq uency, and current of th e motor match the rating on the drive nameplate.

• Use metallic conduit for all drive wiring. Do not run control and power wiring in the same conduit.

• Separate the metallic conduits carrying power wiring from those carrying control wiring by at least 76 mm (3 in.).

• Separate the non-metallic conduits or cable trays carrying power wiring from the metallic conduit carrying control wiring by at least 305 mm (12 in.).

• Whenever power and control wiring cross, the metalli c conduits and non-metallic conduits or trays must cross at right angles.

• Equip all inductive circuits near the drive (such as relays, contactors, and solenoid valves) with noise suppressors.

Branch circuit protection

Refer to NEC Article 430 for sizing of branch circuit conductors. Ensure that all branch circuit components and equipment (such as transformers, feeder cables, disconnect devices, and protecti ve dev i ces) are ra ted fo r the in put current of th e ATV21 dri ve, or for the rated output current, whichever value is larger. The input current of the drives depends on the impedance of the power distribution system and the available short-circuit current at the drive input terminals.

Tables on page 8 provide input current information to op timally size branch circuit conductors. Do not exceed the short- circuit current rating shown in the tables. The short-circuit current rating is the available short-circuit current capability on the line side of the fuses or circuit breakers. A line reactor can be used to add impedance and reduce the available short-circuit current capability to the level allowed by the drive.

Note: Ensure that the branch circuit feeder protection rating is not less than the rated output current of the drive. When more than two drives are installed in parallel on a common powe r line volt age, rega rdles s of volt age rating, an indivi dual line reactor

per drive is recommended. This provides filtering between drives and reduces harmonic distortion when the system is partially loaded. If starting the drive from line power, limit operations of the line contac tor to less tha n once per minute to avoid premature failure of the filter

capacitors and precharge resistor. Use the logic inputs to command the drive.

WARNING

INADEQUATE OVERCURRENT PROTECTION

• Overcurrent protective devices must be properly coordinated.

• The National Electrical Code and the Canadia n Electricity Co de require branch circuit protection. Use t he fuses recommended in the catalogue to achieve published short-circuit current ratings.

• Do not connect the drive to a power feeder whose short-circuit capacity exceeds the drive short-circuit current rating listed on the drive nameplate or in Tables on page

Failure to follow these instructions can result in death, serious injury, or equipment damage.

Wiring

Drive

YES

Output wiring

The drive is sensitive to the amount of capacitance (either phase-to-phase or phase-to-ground) present on the output power conductors. Excessive capacitance can cause an overcurrent trip. Follow these guidelines when selecting output cable:

• Cable type: The cable selected must have a low capacitance phas e-to-phase and phase-to-ground. Do not use mineral-impregnated cable because it has a very high capacitance. Immersion of cables in water increases capacitance.

• Cable length: The longer the cable, the g reater the capacitance. Cabl e lengths greater than 30.5 m (100 f t.) can affect the drive and motor performance.

• When the output cable is in close proximity to other output cables, the dri ve may fault under some cond itions beca use of high frequency switching and increased capacitance.

• Do not use lightning arrestors and/or power factor correction capacitors on the output of the drive.

For proper drive short circuit protection, certain values of indu ctance may be required in the output power wiring. Inductance ca n be supplied by the power wiring or auxiliary inductors.

CAUTION

INSUFFICIENT OUTPUT INDUCTANCE

Provide at least 500 mm (20 in.) of cable at the drive output (U/T1, V/T2, W/T3) to ensure a minimum inductance to protect the drive output from short circuits.

Failure to follow this instruction can result in injury or equipment damage.

Grounding

Ground the drive according to the National Electrical Code and all local codes to ensure safe, dependable operation.

• Connect a copper wire from the equipmen t ground lug o r termi nal t o the power s ystem grou nd condu ctor. Siz e the wire accordi ng to the drive rating and national and local codes.

• Verify that resistance to ground is 1 W or less. Improper grounding causes intermittent and unreliable operation.

DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

Ground the equipment using the provided ground connecting poi nt. The drive panel must be properly grounded b efore power is applied.

Failure to follow this instruction will result in death or serious injury.

Ground multiple drives below. Do not loop the ground cables or connect them in series.

When using the ATV21 drive on a system with an isolated or impedance grounded neutral, use a permanent in sulation mo nitor compatible with non-linear loads.

ATV21 480 V rated drives feature built-in radio frequency interference (RFI) filters with grounded capacitors. When using the drive on an impedance grounded system, we recommend that you isolate the RFI filters from ground to prevent reduction of their operating life.

• ATV21H 075N4 to U55N4, ATV21H D22N4 to D30N4: Pull out the jumpe r to the left of th e ground terminal as illustrat ed below to isolate the RFI filters.

• ATV21H U75N4 to D18N4: Connect the cable to the top left of the power termi nals as illustrated below to isolate the filters.

Motor thermal protection

Thermal protection is integrated into the drive by continuous calculation of I2t, taking motor speed into account. The motor power rating must be between 10% and 100% of the drive rating.

CAUTION

LOSS OF MOTOR OVERLOAD PROTECTION

• Setting the parameter OLn to 2, 3, 6, or 7 (not factory setting) disables the internal motor overload protection function. In th is case,

external motor overload protection must be provided. For more information, refer to the Altivar® 21 Programming Manual.

• When using external overload relays connected to the drive output, the overload relay must be capable of operation across the

expected range of drive output frequencies (including direct current).

• When using DC injection braking, the overload relay must be suitable for operation with direct current flowing in the motor. Do not

use overload relays equipped with current transformers for sensing the motor current.

Failure to follow these instructions can result in injury or equipment damage.

If parameter F632 is set to zero (factory setting), the motor ther mal state memory is reset to zero when the drive i s powered down. For more information, refer to the Altivar® 21 Programming Manual. This drive does not provide direct thermal protection for the motor. Consult the motor manufacturer for the thermal capability of the motor when operated over the desired speed range.

CAUTION

MOTOR OVERHEATING

• If parameter F632 is set to zero (factory setting), the motor thermal state memory is reset to zero when the drive is powered down.

For more information, refer to the Altivar® 21 Programming Manual.

• Use a thermal sensor in the motor as required by the motor manufacturer for protection at all speeds and load conditions.

Failure to follow these instruction can result in injury or equipment damage.

The ATV21 drive is considered to be a component. It is neither a machine nor a piece of equipment ready for use in accordance with the European Community directives (machinery directive or elect romagnetic compati bility directi ve). It is the user’s responsibility to ensure that the machine meets those standards.

Installation recommendations for meeting EN 55011 class A

• Ensure that the grounds of the drive, the motor, and the cable shields are at equal potential.

• Use shielded cables with the shields connected to ground at bot h ends of the motor cable and control cables. Conduit can be used for part of the shielding length, provided that there is no break in continuity.

• Ensure maximum separation between the power supply cable (line supply) and the motor cable.

1 EMC plate supplied with the ATV21 drive. 2 ATV21 drive. 3 Non-shielded power supply wires or cables. 4 Non-shielded wires for the output of the safety relay contacts. 5 The shields for cables 6 and 7 must be securely attached to the EMC plate with

stainless steel clamps (item 5). Strip cables 6 and 7 to expose the shields. Apply appropriately-sized clamps around the stripped porti on of the cables and fasten them to the EMC plate.

6 Shielded cable for connection to the motor, with shield connected to ground at both

ends. This shield must not be interrupted. If intermediate terminal blocks are used, they must be in EMC-shielded metal boxes.

7 Shielded cable for connection to control/command devices. For applications which

require a large number of conductors, small cross-sections must be used (0.5 mm 20 AWG). This shield must not be interrupted. If intermediate terminal blocks are used, they must be in EMC-shielded metal boxes.

8 Ground screw. Use this screw for the motor cables on the low power rated drives, as

the ground screw on the heatsink is inaccessible.

If using an additional input filter, connect it directl y to the l ine supply wi th an unsh ielded cable. Then make connection 3 on the drive using the filter output cable. Although there is a high frequency equipotential ground connection between the drive, motor, and cable shielding, you must still connect the PE protect ive conducto rs (greenyellow) to the appropriate terminals on each of the devices. You may also need to disconnect the shield at the motor end for very long cable runs to alleviate noise generation.
