The drive is an electronic motor controller intended for:
•Regulation of motor speed in response to system feedback or to remote commands from external controllers. A power-drive system consists of the drive, the motor, and equipment driven by the motor.
•System and motor status surveillance.
The drive can also be used for motor protection.
Depending on the configuration, the drive can be used in standalone applications or form part of a larger appliance or installation.
The VLT® Decentral Drive FCD 302 is designed for decentral mounting, for example, in the food and beverage industry, or for other material handling applications. With the FCD 302, it is possible to reduce costs by placing the power electronics decentrally. Central panels are then rendered obsolete, saving cost, space, and effort for installation and wiring. The basic design is service-friendly with a pluggable electronic part and a flexible and spacious wiring box. It is easy to change electronics without the need for rewiring.
Installation environment: The drive is allowed for use in residential, industrial, and commercial environments in accordance with local laws and standards.
N O T I C E
RADIO INTERFERENCE
In a residential environment, this product can cause radio interference, in which case supplementary mitigation measures can be required.
-Take the necessary precautions.
Foreseeable misuse
Do not use the drive in applications which are non-compliant with specified operating conditions and environments. Ensure compliance with the conditions specified in 7.4.1 Environment.

W A R N I N G
HIGH VOLTAGE
AC drives contain high voltage when connected to AC mains input, DC supply, or load sharing. Failure to perform installation, start-up, and maintenance by qualified personnel can result in death or serious injury.
-Only qualified personnel must perform installation, start-up, and maintenance.
W A R N I N G
UNINTENDED START
When the drive is connected to the AC mains, the motor may start at any time, causing risk of death, serious injury, and equipment or property damage. The motor may start by activation of an external switch, a fieldbus command, an input reference signal from the LCP or LOP, via remote operation using MCT 10 Set-up software, or after a cleared fault condition.
-Press [Off] on the LCP before programming parameters.
-Disconnect the drive from the mains whenever personal safety considerations make it necessary to avoid unintended motor start.
-Check that the drive, motor, and any driven equipment are in operational readiness.
W A R N I N G
DISCHARGE TIME
The drive contains DC-link capacitors, which can remain charged even when the drive is not powered. High voltage can be present even when the warning indicator lights are off.
Failure to wait the specified time after power has been removed before performing service or repair work could result in death or serious injury.
-Stop the motor.
-Disconnect AC mains, permanent magnet type motors, and remote DC-link supplies, including battery back-ups, UPS, and DC-link connections to other drives.
-Wait for the capacitors to discharge fully. The time for full discharge of the capacitors is minimum 4 minutes for VLT® Decentral Drive FCD 302, 400 V AC, 0.37–3.0 kW (0.5–4.0 hp).
-Before performing any service or repair work, use an appropriate voltage measuring device to make sure that the capacitors are fully discharged.
C A U T I O N
INTERNAL FAILURE HAZARD
An internal failure in the drive can result in serious injury when the drive is not properly closed.
-Ensure that all safety covers are in place and securely fastened before applying power.

W A R N I N G
ELECTRICAL HAZARD
Applying power to the unit at this stage could result in death or serious injury.
-Do not apply power before the electrical installation is complete.
W A R N I N G
PERSONAL INJURY OR PROPERTY DAMAGE
Do not switch on the mains before the 4 screws are tightened. Failure to tighten these screws can result in personal injury or material damage when the unit is loaded.
-Tighten screws before switching on power.
-Ensure that the strength of the mounting location can support the unit weight.
•Use the holes on the rear of the installation box to fix mounting brackets.
•Use proper mounting screws or bolts.
•For hygienic versions, use cable glands designed to meet hygienic application requirements, for example Rittal HD 2410.110/120/130.

See 2.1 Safety Precautions for general safety instructions.
W A R N I N G
INDUCED VOLTAGE
Induced voltage from output motor cables that run together can charge equipment capacitors, even with the equipment turned off and locked out. Failure to run output motor cables separately or to use shielded cables could result in death or serious injury.
-
-
Run output motor cables separately or use shielded cables. Simultaneously lock out all the drives.
W A R N I N G
SHOCK HAZARD
The unit can cause a DC current in the PE conductor. Failure to use a Type B residual current-operated protective device (RCD) may lead to the RCD not providing the intended protection and therefore may result in death or serious injury.
-When an RCD is used for protection against electrical shock, only a Type B device is allowed on the supply side.
Overcurrent protection
•Extra protective equipment, such as short-circuit protection or motor thermal protection between drive and motor, is required for applications with multiple motors.
•Input fusing is required to provide short circuit and overcurrent protection. If not factory-supplied, the installer must provide fuses. See maximum fuse ratings in 7.7.2 Recommended Maximum Pre-fuse Size 25 A.
Wire type and ratings
•All wiring must comply with local and national regulations regarding cross-section and ambient temperature requirements.
•Power connection wire recommendation: Minimum 75 °C (167 °F) rated copper wire. See 7.1 Electrical Data for recommended wire sizes and types.
To obtain an EMC-compliant installation, follow the instructions provided in 4.3 Grounding, 4.4 Wiring Schematic, 4.7 Connecting the Motor, and 4.10.1 Control Wiring.
N O T I C E
POTENTIAL EQUALIZATION
Risk of burst transient when the ground potential between the drive and the control system is different. Install equalizing cables between the system components. Recommended cable cross-section: 16 mm2 (6 AWG).
For electrical safety
•Ground the drive in accordance with applicable standards and directives.
•Use a dedicated ground wire for input power, motor power, and control wiring.
•Do not ground 1 drive to another in a daisy chain fashion.
•Keep the ground wire connections as short as possible.
•Follow motor manufacturer's wiring requirements.
•Minimum cable cross-section: 10 mm2 (7 AWG) (or 2 rated ground wires terminated separately).

•Establish electrical contact between the cable shield and the drive enclosure by using metal cable glands or by using the clamps provided on the equipment.
•Use high-strand wire to reduce electrical interference.
•Do not use pigtails.

Risk of burst transient when the ground potential between the drive and the control system is different. Install equalizing cables between the system components. Recommended cable cross-section: 16 mm2 (6 AWG).
C A U T I O N
PE CONNECTION
The metal pins in the corners of the electronic part and the holes on the corner of the installation box are essential for the protective earth connection. Make sure that they are not loosened, removed, or violated in any way. Tightening torque requirement is 3 Nm (26.6 in-lb).
