2.6 Mechanical Installation Precautions

W A R N I N G

EXPLOSIVE ATMOSPHERE

Installing the drive in a potentially explosive atmosphere can lead to death, personal injury, or property damage.

-Install the unit in a cabinet outside of the potentially explosive area.

-Use a motor with an appropriate ATEX protection class.

-Install a PTC temperature sensor to an ATEX PTC-Thermistor device to monitor the motor temperature.

-Install short motor cables.

-Use sine-wave output filters when shielded motor cables are not used.

2.7 Electrical Installation Precautions

Before you do electrical work on the drive, lock out and tag out all power sources to the drive.

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/tagged 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/tag out all the drives.

Protective earth connection and RCD requirements

A properly dimensioned protective earth (PE) setup is essential for the safety of the drive system protecting the user against electrical shock. The PE connections of the drive installation ensure that the drive system remains safe preventing that the single fault currents will generate any hazardous voltages on accessible conductive part, for example, conductive enclosure parts.

The VLT® AutomationDrive EZ FC 321 shall be installed according to the requirement for PE connection and supplementary protective bonding as specified in IEC/EN 60364-5-54 cl. 543 and 544.

For the automatic disconnection, if there is a fault at the motor side, it shall also be ensured that the impedance of the PE connection between drive and motor is sufficiently low to ensure compliance with IEC/EN 60364-4-41 cl. 411 or 415. The impedance is verified by initial and periodic test according to IEC 60364-4-41.

In some regions, extra local requirements apply and must be adhered to.

The suitability for connection of PE and protective bonding of accessible conductive parts according to IEN/EN 60364-5-54 to the drive is ensured by following the design according to IEC/EN 61800-5-1.

Where the FC 321 is used as a component inside specific applications, special requirement for proper connection to the PE may apply, for example, IEC/EN 60204 and IEC/EN 61349-1.

W A R N I N G

ELECTRICAL SHOCK HAZARD - LEAKAGE CURRENT HAZARD >3.5 MA

Leakage currents exceed 3.5 mA. Failure to connect the drive properly to protective earth (PE) can result in death or serious injury.

-Ensure reinforced protective earthing conductor according to IEC 60364-5-54 cl. 543.7 or according to local safety regulations for high touch current equipment. The reinforced protective earthing of the can be done with:

-a PE conductor with a cross-section of at least 10 mm2 (8 AWG) Cu or 16 mm2 (6 AWG) Al

-an extra PE conductor of the same cross-sectional area as the original PE conductor as specified by IEC 60364-5-54 with a minimum cross-sectional area of 2.5 mm2 (14 AWG) (mechanical protected) or 4 mm2 (12 AWG) (not mechanical protected).

-a PE conductor completely enclosed with an enclosure or otherwise protected throughout its length against mechanical damage.

-a PE conductor part of a multi-conductor power cable with a minimum PE conductor cross-section of 2.5 mm2 (14 AWG) (permanently connected or pluggable by an industrial connector. The multi-conductor power cable shall be installed with an appropriate strain relief).

-NOTE: In IEC/EN 60364-5-54 cl. 543.7 and some application standards (for example IEC/EN 60204-1), the limit for requiring reinforced protective earthing conductor is 10 mA leakage current.

W A R N I N G

ELECTRICAL SHOCK HAZARD - LEAKAGE CURRENT

Leakage currents can exceed 5%. Failure to ground the drive properly can result in death or serious injury.

-When the leakage currents exceed 5%, the protective earth (PE) shall be oversized by one number according to IEC/EN 60364-5-54 cl. 543.

-Ensure that the minimum size of the ground conductor complies with local safety regulations.

W A R N I N G

ELECTRICAL SHOCK AND FIRE HAZARD - RCD COMPLIANCE

The unit can cause a DC fault 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, fire, or other serious hazard.

-When an RCD is used for protection against electrical shock or against fire, only a Type B device is allowed on the supply side.

Other precautions

C A U T I O N

THERMISTOR INSULATION

Risk of personal injury or equipment damage.

-To meet PELV insulation requirements, use only thermistors with reinforced or double insulation.

N O T I C E

EXCESSIVE HEAT AND PROPERTY DAMAGE

Overcurrent can generate excessive heat within the drive. Failure to provide overcurrent protection can result in risk of fire and property damage.

-Other protective devices such as short-circuit protection or motor thermal protection between drive and motor are required for applications with multiple motors.

-Input fusing is required to provide short circuit and overcurrent protection. If fuses are not factory-supplied, the installer must provide them. See 4.11 Fuses and Circuit Breakers for fuse specifications.
