NOTICE
FUNCTIONAL SAFETY OPTIONS
Functional safety options require additional wiring and parameter
configuration. Refer to the specific functional safety operating guide, such
as the Safe Torque Off Operating Guide, for more information on how to install
the safety option.
Qualified Personnel
Only qualified personnel are allowed to install, commission, and maintain
Danfoss drives. Qualified personnel are trained individuals who are familiar
with and authorized to mount and wire the drive in accordance with pertinent
laws and regulations. Also, qualified personnel must be familiar with the
instructions and safety measures described in this installation guide.
Safety Symbols
The following symbols are used in this guide:
- DANGER: Indicates a hazardous situation that, if not avoided, will result in death or serious injury.
- WARNING : Indicates a hazardous situation which, if not avoided, could result in death or serious injury.
- CAUTION: Indicates a hazardous situation which, if not avoided, could result in minor or moderate injury.
- NOTICE : Indicates information considered important, but not hazard-related (for example, messages relating to property damage).
Safety Precautions
WARNING
LACK OF SAFETY AWARENESS
This guide gives important information on preventing injury and damage to the
equipment or the system. Ignoring this informa-tion 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.
- Before performing any electrical work on the drive, lock out and tag out all power sources to the drive.
WARNING
LIFTING HEAVY LOAD
The drive is heavy. Lifting heavy objects incorrectly can result in death,
injury, or property damage.
- Follow local safety regulations on lifting.
- Check the weight of the drive. The weight is provided on the outside of the shipping box.
- If lifting equipment is used, ensure that it is in proper working condition and can safely lift the weight of the drive. Test lift the drive to verify the proper center of gravity lift point. Reposition if not level.
WARNING
HAZARDOUS VOLTAGE
AC drives contain hazardous voltage when connected to the AC mains or
connected to the DC terminals. 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.
WARNING
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 can result in death or
serious injury.
- Stop the motor.
- Disconnect all power sources, including permanent magnet-type motors.
- Wait for capacitors to discharge fully. The discharge time is shown on the nameplate. See Illustration 1. Verify full discharge by measuring the voltage level.
WARNING
UNINTENDED START
When the drive is connected to the AC mains or connected to the DC terminals,
the motor may start at any time, causing a 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 mains whenever safety considerations make it necessary to avoid unintended motor start.
- Check that the drive, motor, and any driven equipment are in operational readiness.
CAUTION
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.
WARNING
ELECTRICAL SHOCK AND FIRE HAZARD
The drive can cause a DC in the ground conductor. Failure to use a Type B
residual current-operated protective device (RCD) can lead to the RCD not
providing the intended protection which can result in death, fire, or other
serious hazard.
- Use an RCD device.
- When an RCD is used for protection against electrical shock or fire, use only a Type B device on the supply side.
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.
WARNING
ELECTRICAL SHOCK HAZARD
Due to the stray capacitance of the shielded motor cable, the leakage currents
exceed 3.5 mA. Failure to properly ground the drive can result in death or
serious injury.
- Ensure that the minimum size of the ground conductor complies with the local safety regulations for high-touch current equipment.
- Use a reinforced ground conductor according to IEC 60364-5-54 cl. 543.7 or local safety regulations for equipment with leak-age current >3.5 mA.
- For reinforced grounding:
Use a ground conductor with a cross-section of at least 10 mm2 (8 AWG) Cu or 16 mm2 (6 AWG) Al, or an extra ground conductor of the same cross-sectional area as the original ground conductor as specified by IEC 60364-5-54, with a minimum cross-sectional area of 2.5 mm2 (14 AWG) mechanically protected or 4 mm2 (12 AWG) not mechanically protected.
Use a ground conductor inside an enclosure or otherwise protected throughout its length against mechanical damage. Use a ground conductor that is part of a multi-conductor power cable with a minimum PE conductor cross-section of 2.5 mm2 (14 AWG) that is permanently connected or plugged in by an industrial connector. The multi-conductor power cables must be installed with an appropriate strain relief.
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.
NOTICE
EXCESSIVE HEAT AND PROPERTY DAMAGE
Overcurrent can generate excessive heat within the drive. Failure to provide
overcurrent protection can result in a risk of fire and property damage.
- Use additional protective devices such as short-circuit protection or motor thermal protection between the drive and the motor 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.
NOTICE
PROPERTY 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.
Required Tools
- Lifting aid
- Tape measure
- Drill with assorted bits
- Screwdrivers (Torx, Phillips, slotted)
- Wrench with 7–17 mm sockets
- Socket extensions
- Sheet metal punch and/or pliers Wire crimper
Verifying the Shipment and the Contents
Make sure that the items supplied and the information on the nameplate located
on the exterior of the enclosure match the order.
NOTICE
The type code is used in the fuse table. Write down the type code and
serial number for future reference.

EMC-compliant Installation
For more information, refer to the product-specific operating guide.
- Use shielded cables for the motor (unshielded cables in the metal conduit are acceptable), brake, DC, and control wiring.
- Ensure that the motor, brake, and DC cables are as short as possible to reduce the interference level from the entire system. Provide a minimum space of 200 mm (7.9 in) between mains input, motor cables, and control cables.
- Convey the currents back to the drive using a metal mounting plate. Ensure good electrical contact from the mounting plate through the mounting screws to the metal frame of the enclosure.
- If the shield connection points have a voltage potential difference, connect a low impedance equalizing wire parallel to the shielded cable.
- 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.
Installing the Drive
The installation location is important.
Full output current is available when the following installation conditions
are met. For temperatures and altitudes outside this range, consult the
Derating section in the VLT® Lift Drive LD 302 Operating Instructions.
- Maximum surrounding air temperature: 45 ºC (113 ºF) average over 24 hours and 50 ºC (122 ºF) for 1 hour.
