4.4 Operating Environment

NOTICE!

In environments with airborne liquids, particles, or corrosive gases, ensure that the IP/type rating of the equipment matches the installation environment. Failure to meet requirements for ambient conditions can reduce

4 4 the lifetime of the drive. Ensure that requirements for air humidity, temperature, and altitude are met.

Voltage [V]	Altitude restrictions
380–480	At altitudes above 3000 m (9842 ft), contact
	Danfoss regarding PELV.

Table 4.1 Installation at High Altitudes

For detailed ambient conditions speci€cations, refer to chapter 10.4 Ambient Conditions.

NOTICE!

CONDENSATION

Moisture can condense on the electronic components and cause short circuits. Avoid installation in areas subject to frost. Install an optional space heater when the drive is colder than the ambient air. Operating in standby mode reduces the risk of condensation as long as the power dissipation keeps the circuitry free of moisture.

NOTICE!

EXTREME AMBIENT CONDITIONS

Hot or cold temperatures compromise unit performance and longevity.

•Do not operate in environments where the ambient temperature exceeds 55 °C (131 °F).

•The drive can operate at temperatures down to -10 °C (14 °F). However, proper operation at rated load is only guaranteed at 0 °C (32 °F) or higher.

•If temperature exceeds ambient temperature limits, extra air conditioning of the cabinet or installation site is required.

4.4.2 Dust

When installing the drive in dusty environments, pay attention to the following:

Periodic maintenance

When dust accumulates on electronic components, it acts as a layer of insulation. This layer reduces the cooling capacity of the components, and the components become warmer. The hotter environment decreases the life of the electronic components.

Keep the heat sink and fans free from dust buildup. For more service and maintenance information, refer to chapter 9 Maintenance, Diagnostics, and Troubleshooting.

Cooling fans

Fans provide airflow to cool the drive. When fans are exposed to dusty environments, the dust can damage the fan bearings and cause premature fan failure. Also, dust can accumulate on fan blades causing an imbalance which prevents the fans from properly cooling the unit.

4.4.3 Potentially Explosive Atmospheres

WARNING

EXPLOSIVE ATMOSPHERE

Do not install the drive in a potentially explosive atmosphere. Install the unit in a cabinet outside of this area. Failure to follow this guideline increases risk of death or serious injury.

4.5 Installation and Cooling Requirements

NOTICE!

MOUNTING PRECAUTIONS

Improper mounting can result in overheating and reduced performance. Observe all installation and cooling requirements.

4.4.1 Gases

Aggressive gases, such as hydrogen sul€de, chlorine, or ammonia can damage the electrical and mechanical components. The unit uses conformal-coated circuit boards to reduce the effects of aggressive gases. For conformalcoating class speci€cations and ratings, see

chapter 10.4 Ambient Conditions.

Mechanical Installation	Operating Guide

Installation Requirements

•Ensure unit stability by mounting vertically to a solid flat surface.

•Ensure that the strength of the mounting location supports the unit weight. Refer to

chapter 3.2 Power Ratings, Weights, and Dimensions.

•Ensure the mounting location allows access to open the enclosure door. See

chapter 10.9 Enclosure Dimensions.

•Ensure that there is adequate space around the unit for cooling airflow.

•Place the unit as near to the motor as possible. Keep the motor cables as short as possible. See chapter 10.5 Cable Specifications.

•Ensure the location allows for cable entry at the bottom of the unit.

Cooling and Airflow Requirements

•Ensure that top and bottom clearance for air cooling is provided. Clearance requirement: 225 mm (9 in).

•Consider derating for temperatures starting between 45 °C (113 °F) and 50 °C (122 °F) and elevation 1000 m (3300 ft) above sea level. See the product-speci€c design guide for detailed information.

The drive uses back-channel cooling to circulate the heat sink cooling air. The cooling duct can carries approximately 90% of the heat out of the back channel of the drive. Redirect the back-channel air from the panel or room by using:

•	Duct cooling. Back-channel cooling kits are
	available to direct the air away from the panel	4	4
	when an IP20/chassis drive is installed in a Rittal

enclosure. Use of a kit reduces the heat in the panel and smaller door fans can be speci€ed on the enclosure.

5.1 Safety Instructions

See chapter 2 Safety for general safety instructions.

WARNING

5 5

INDUCED VOLTAGE

Induced voltage from output motor cables from different drives that run together can charge equipment capacitors even with the equipment turned off and locked out. Failure to run output motor cables separately or use shielded cables or metal conduits could result in death or serious injury.

•Run output motor cables separately or use shielded cables.

•Simultaneously lock out all the drives.

WARNING

SHOCK HAZARD

The drive can cause a DC current in the ground conductor and thus result in death or serious injury.

•When a residual current-operated protective device (RCD) is used for protection against electrical shock, only an RCD of Type B is allowed on the supply side.

Failure to follow the recommendation means that the

RCD cannot provide the intended protection.

NOTICE!

The drive is supplied with Class 20 motor overload protection.

Overcurrent protection

•Additional protective equipment such as shortcircuit 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 fuses are not factory-supplied, the installer must provide them. See maximum fuse ratings in chapter 10.7 Fuses and Circuit Breakers.

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 chapter 10.5 Cable Specifications for recommended wire sizes and types.

CAUTION

PROPERTY DAMAGE

Protection against motor overload is not included in the default setting. To add this function, set

parameter 1-90 Motor Thermal Protection to [ETR trip] or

[ETR warning]. For the North American market, the ETR function provides class 20 motor overload protection in accordance with NEC. Failure to set parameter 1-90 Motor Thermal Protection to [ETR trip] or [ETR warning] means that motor overload protection is not provided and, if the motor overheats, property damage can occur.

5.2 EMC-compliant Installation

To obtain an EMC-compliant installation, follow the instructions provided in:

•chapter 5.3 Wiring Schematic.

•chapter 5.4 Connecting to Ground.

•chapter 5.5 Connecting the Motor.

•chapter 5.6 Connecting the AC Mains.

NOTICE!

TWISTED SHIELD ENDS (PIGTAILS)

Twisted shield ends (pigtails) increase the shield impedance at higher frequencies, reducing the shield effect and increasing the leakage current. To avoid twisted shield ends, use integrated shield clamps.

•For use with relays, control cables, a signal interface, €eldbus, 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.

MG06I122

Electrical Installation	Operating Guide

•Use shielded cables for motor output cables. An alternative is unshielded motor cables within metal conduit.

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.

•

•

•

•

Ensure that motor and brake cables are as short 5 5 as possible to reduce the interference level from

the entire system.

Avoid placing cables with a sensitive signal level alongside motor and brake 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!

EMC INTERFERENCE

Run cables for mains input, motor wiring, and control wiring in 3 separate metallic conduits. Failure to isolate power, motor, and control cables can result in unintended behavior or reduced performance. Minimum 200 mm (7.9 in) clearance between mains input, motor, and control cables are required.

NOTICE!

INSTALLATION AT HIGH ALTITUDE

There is a risk for overvoltage. Isolation between components and critical parts could be insufficient, and not comply with PELV requirements. Reduce the risk for overvoltage by using external protective devices or galvanic isolation.

For installations above 2000 m (6500 ft) altitude, contact Danfoss regarding PELV compliance.

NOTICE!

PELV COMPLIANCE

Prevent electric shock by using protective extra low voltage (PELV) electrical supply and complying with local and national PELV regulations.
