2.6 Mechanical Installation Precautions
WARNING
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.
WARNING
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.

WARNING
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 regula-
tions 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.

WARNING
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

Electrical Installation

4 Electrical Installation
4.1 EMC-compliant Installation
To obtain an EMC-compliant installation, refer to the wiring schematic (see Illustration 5) and follow the electrical installation instructions. Also, remember to practice the following: · When using relays, control cables, a signal interface, fieldbus, or brake, connect the shield to the enclosure at both ends. If the
ground path has high impedance, is noisy, or is carrying current, break the shield connection on 1 end to avoid ground current loops. · Convey the currents back to the unit using a metal mounting plate. Ensure good electrical contact from the mounting plate through the mounting screws to the drive chassis. · Use shielded cables for motor output cables. An alternative is unshielded motor cables within metal conduit. · Ensure that motor and brake cables are as short as possible to reduce the interference level from the entire system. · Provide a minimum 200 mm (7.9 in) separation between mains input, motor cables, and control cables. · For communication and command/control lines, follow the particular communication protocol standards. For example, USB must use shielded cables, but RS485/ethernet can use shielded UTP or unshielded UTP cables. · Ensure that all control terminal connections are PELV.
NOTICE
TWISTED SHIELD ENDS (PIGTAILS) Twisted shield ends increase the shield impedance at higher frequencies, which reduces the shield effect and increases the leakage current.
– Use integrated shield clamps instead of twisted shield ends.
NOTICE
SHIELDED CABLES If shielded cables or metal conduits are not used, the unit and the installation do not meet regulatory limits on radio frequency (RF) emission levels.
NOTICE
EMC INTERFERENCE Failure to isolate power, motor, and control cables can result in unintended behavior or reduced performance.
– Use shielded cables for motor and control wiring. – Provide a minimum 200 mm (7.9 in) separation between mains input, motor cables, and control cables.
NOTICE
INSTALLATION AT HIGH ALTITUDE There is a risk for overvoltage. Isolation between components and critical parts could be insufficient and may not comply with PELV requirements.
– Use external protective devices or galvanic isolation. For installations above 2000 m (6500 ft) altitude, contact Danfoss re-
garding protective extra low voltage (PELV) compliance.
NOTICE
PROTECTIVE EXTRA LOW VOLTAGE (PELV) COMPLIANCE Prevent electric shock by using PELV electrical supply and complying with local and national PELV regulations.

WARNING
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.
· Run output motor cables separately or · Use shielded cables. · Comply with local and national electrical codes for cable sizes. For maximum wire sizes, see 4.2 Cable Specifications. · Follow motor manufacturer wiring requirements. · Motor wiring knockouts or access panels are provided at the base of IP55 (NEMA 12) units. · Do not wire a starting or pole-changing device (for example a Dahlander motor or slip ring asynchronous motor) between the
drive and the motor.

4.11 Fuses and Circuit Breakers
4.11.1 Fuse Recommendations
Fuses ensure that possible damage to the drive is limited to damages inside the unit. Danfoss recommends fuses and/or circuit breakers on the supply side as protection. For further information, see the application guide Fuses and Circuit Breakers.
NOTICE
Use of fuses on the supply side is mandatory for IEC 60364 (CE) and NEC 2009 (UL) compliant installations.

Recommendations
· gG type fuses.
· Eaton/Moeller type circuit breakers. For other circuit breaker types, ensure that the energy into the drive is equal to or lower than the energy provided by Eaton/Moeller types.
For further information, see the application guide Fuses and Circuit Breakers. The recommended CE and UL compliant fuses are suitable for use on a circuit capable of 100000 Arms (symmetrical), depending on the drive voltage rating. With the proper fusing, the drive short circuit current rating (SCCR) is 100000 Arms.

All digital inputs are galvanically isolated from the supply voltage (PELV) and other high-voltage terminals.
When using a contactor with a DC coil inside in combination with STO, it is important to make a return way for the current from the coil when turning it off. This can be done by using a freewheel diode (or, alternatively, a 30 V or 50 V MOV for quicker response time) across the coil. Typical contactors can be bought with this diode.
