LACK OF SAFETY AWARENESS
This guide provides important information on preventing injury and damage to the equipment or the system. Ignoring this information can lead to death, serious injury, or severe damage to the equipment.
- Make sure to fully understand the dangers and safety measures present in the application.
WARNING
ELECTRIC SHOCK
Drives contain hazardous voltage when a power source is connected to AC or DC terminals. Failure to disconnect all power sources can result in death or serious injury.
- Before performing any electrical work on the drive, disconnect, lock out, and tag out all power sources to the drive.
- There is more than one live circuit. See the relevant wiring diagram in the product guide.
WARNING
DISCHARGE TIME
The drive contains 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 drive.
- Disconnect all input and output power sources of the drive (for example permanent magnet type motors, batteries, or DC-link connections to other drives).
- Wait for the capacitors to discharge fully before performing any service on the equipment. The discharge time is 5 minutes. If the device is broken or fuses have tripped, the discharge time is longer.
- Use a measuring device to make sure that there is no voltage, before opening the drive or performing any work on the cables.
WARNING
UNINTENDED START
When the drive is connected to a power source, the system may start at any time, causing risk of death, serious injury, and equipment or property damage.
- Stop the drive and motor before configuring parameters.
- Make sure that the drive cannot be started by an external switch, a fieldbus command, an input reference signal from the control panel, or after a cleared fault condition.
- Disconnect the drive from the power source whenever safety considerations make it necessary to avoid unintended start.
- Check that the drive, motor, and any driven equipment are in operational readiness.
Lifting Safety
WARNING
LIFTING HEAVY LOAD
Not following the safe lifting instructions can result in death or serious injury and damage to the equipment.
- Follow local safety regulations on lifting.
- Use a lifting device that is in proper working condition and appropriate for the weight of the load.
- Test lift the load to verify the proper center of gravity. Reposition the lifting point if not level.
- Do not walk under, or place any part of your body under a suspended load.
WARNING
SWINGING HAZARD DURING LIFTING
The swing effect can cause serious injury and damage to the equipment. It occurs when lifting the product into a vertical position, just before the product reaches vertical position, when the center of gravity of the product surpasses the floor support point.
- Make sure that the lifting ropes are properly attached.
- Secure the lifting area.
- Lift the product slowly and carefully.
Mechanical Installation Safety
WARNING
ELECTRIC SHOCK WITHOUT ENCLOSURE
The IP00/Open Type drives do not have protective covers over all live components. Touching live components can cause death or serious injury.
- Install IP00/Open Type drives inside a cabinet or other enclosure that provides appropriate protection.
WARNING
BURN OR FIRE HAZARD WITHOUT ENCLOSURE
The IP00/Open Type drives do not provide comprehensive mitigation for burn or fire hazards.
- Install IP00/Open Type drives inside a cabinet or other enclosure that provides appropriate protection. Installing the drives into enclosures prevents the personnel from touching hot surfaces, and the spreading of a possible fire.
Electrical Installation Safety
WARNING
BRANCH CIRCUIT HAZARD
Unprotected branch circuits can cause an electrical or a fire hazard.
- Internal short circuit protection does not provide branch circuit protection. To protect the installation, all branch circuits in an installation, switchgear, and machines must be protected against short circuits and overcurrent according to national or international regulations.
WARNING
SHORT-CIRCUIT HAZARD
Unprotected drive system can cause an electrical or a fire hazard.
- Protect the drive system against short circuits. To protect the unit, use the fuses that are required by the manufacturer. The drive system provides full short-circuit protection against a short circuit on the motor output.
WARNING
ELECTRIC SHOCK HAZARD
The drive can cause a DC current in the PE conductor. Failure to use a Type B residual current-operated device (RCD) can lead to death or serious injury.
- When an RCD is used for protection against electric shock, only an RCD of Type B is allowed on the supply side.
WARNING
INDUCED VOLTAGE
Induced voltage from output motor cables that run together or near other power cables can charge equipment capacitors, even with the mains power turned off and locked out. Failure to run output motor cables separately, or to use shielded cables, could result in death or serious injury.
- Install output motor cables in separate conduits or use shielded cables.
WARNING
ELECTRICAL SHOCK HAZARD – HIGH LEAKAGE CURRENT
Leakage currents exceed 3.5 mA. Failure to connect the system properly to protective earth may 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 drive can be done with:
- PE conductor with a cross-section of at least 10 mm2 Cu or 16 mm2 Al.
- PE conductor completely enclosed within an enclosure or otherwise protected throughout its length against mechanical damage.
WARNING
DIFFERENT TYPE OF FUSES
Using a different type of fuse than required can cause a fire.
- Replace fuses with the same type of fuse.
WARNING
OVERHEATED CABLES HAZARD
Incorrect cable installation or environmental conditions can cause cables to overheat. Overheated cables are a fire hazard.
- Use overload protection. The drive system is equipped with an internal overcurrent protection that can be used for upstream overload protection.
- To provide the overcurrent protection, use fuses or circuit breakers.
- Perform overcurrent protection according to local regulations.
- Use symmetrical power cabling with power units connected in parallel. Each power unit must have the same number of cables with an equal cross-section and equal length.
- Install cables according to local regulations and IEC/EN standards.
CAUTION
THERMISTOR INSULATION
Risk of personal injury or equipment damage.
- To meet the PELV insulation requirements, use only thermistors with reinforced or double insulation.
NOTICE
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.
- Additional protective devices 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 fuses are not factory-supplied, the installer must provide them. Refer to the product-specific documentation for fuse specifications.
NOTICE
MOTOR DAMAGE
Protection against motor overload is not active by default. The ETR function provides class 20 motor overload protection. Failure to set the ETR function means that motor overload protection is not provided and property damage can occur if the motor overheats.
- Enable the ETR function. See the application guide for more information.
