WARNING
HAZARDOUS VOLTAGE
AC drives contain hazardous voltage when connected to the AC mains or connected on the DC terminals. Failure to perform
installation, start-up, and maintenance by skilled personnel can result in death or serious injury.
Only skilled 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 exterior of the drive.
Measure the voltage level to verify full discharge.
WARNING
UNINTENDED START
When the drive is connected to the AC mains or connected on the DC terminals, the motor 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 cannnot be started by external switch, a fieldbus command, an input reference signal from the con-
trol 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.
1.5 Electrical Installation Precautions
Before starting electrical work on the drive, lock out and tag out all power sources to the drive.
WARNING
ELECTRICAL SHOCK AND FIRE HAZARD – RCD COMPLIANCE
The drive can cause a DC fault current in the PE conductor. Failure to use a Type B residual current-operated protective device
(RCD) can lead to the RCD not providing the intended protection and therefore can 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.

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 - LEAKAGE CURRENT HAZARD
Leakage currents exceed 3.5 mA. Failure to connect the drive properly to protective earth (PE) can result in death or serious in-
jury.
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 drive 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) (mechanically protected) or 4 mm2(12 AWG) (not mechanically protec-
ted).
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.
CAUTION
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 risk of fire and
property damage.
Additional protective devices such as short circuit protection or motor thermal protection between drive and motor is re-
quired 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 included in the default setting. The ETR function provides class 20 motor overload pro-
tection. 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 programming guide for more information.

1.8 EMC-compliant Installation
For more information, refer to the product-specific operating guide.
Use shielded cables for motor (unshielded cables in metal conduit are acceptable), brake, DC, and control wiring.
Ensure that 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.
1.9 Installing the Drive
Installation location is very important. Full output current is available when the following installation conditions are met:
Maximum surrounding air temperature is 45 °C (113 °F) average over 24 hours and 50 °C (122 °F) for 1 hour.
Minimum surrounding air temperature is 0 °C (32 °F).
Altitude is less than 1000 m (3280 ft) above sea level.
For temperatures and altitudes outside this range, consult the operating guide.
Procedure
Identify the drive. See 1.1.7 Verifying the Shipment and the Contents.
