14 Safety instructions
General safety in installation, start-up and maintenance
These instructions are for all personnel that install the drive and do maintenance work
on it.
WARNING! Follow these instructions. If you ignore them, injury or death, or
damage to the equipment can occur.
• Handle the drive carefully.
• Use safety shoes with a metal toe cap to avoid foot injury.
• Keep the drive in its package or protect it otherwise from dust and burr from
drilling and grinding until you install it.
• Protect also the installed drive against dust and burr. Electrically conductive
debris inside the drive may cause damage or malfunction.
• Vacuum clean the area below the drive before the start-up to prevent the drive
cooling fan from drawing the dust inside the drive.
• Do not cover the air inlet and outlet when the drive runs.
• Make sure that there is sufficient cooling. For more information, see sections
Checking the installation site on page 51 and Losses, cooling data and noise on
page 117.
• Before you connect voltage to the drive, make sure that the drive covers are on.
Keep the covers on during the operation.
• Before you adjust the drive operation limits, make sure that the motor and all
driven equipment can operate throughout the set operation limits.
• Before you activate automatic fault reset functions of the drive control program,
make sure that no dangerous situations can occur. These functions reset the
drive automatically and continue operation after a fault.
• The maximum number of drive power-ups is five in ten minutes. Too frequent
power-ups can damage the charging circuit of the DC capacitors. The maximum
number of times the circuit can charge is: 100000 (frames R1-R2) and 50000
(frames R3-R4).
If you have connected safety circuits to the drive (for example, emergency stop and
Safe torque off), validate them at the start up.
Note:
• If you select an external source for start command and it is On, the drive will start
immediately after fault reset, unless you configure the drive for pulse start.
• When the control location is not set to Local, the stop key on the control panel will
not stop the drive.
Drives can be repaired only by an authorized person.

Electrical safety in installation, start-up and maintenance
Precautions before electrical work
These warnings are for all personnel who do work on the drive, motor cable or motor.
WARNING! Follow these instructions. If you ignore them, injury or death, or
damage to the equipment can occur. If you are not a qualified electrician, do
not do the electrical installation or maintenance work. Go through these steps before
you begin any installation or maintenance work.
1. Clearly identify the work location.
2. Disconnect all possible voltage sources.
• Open the main disconnector at the power supply of the drive.
• Make sure that reconnection is not possible. Lock the disconnector to open
position and attach a warning notice to it.
• Disconnect any external power sources from the control circuits before you do
work on the control cables.
CAUTION - Risk of electric shock. After disconnecting the input power, always
wait for 5 minutes to let the intermediate circuit capacitors discharge before you
start working on the drive, motor or motor cable.
3. Protect any other energized parts in the work location against contact.
4. Take special precautions when close to bare conductors.
5. Measure that the installation is de-energized.
• Use a multimeter with an impedance of at least 1 Mohm.
• Make sure that the voltage between the drive input power terminals (L1, L2,
L3) and the grounding terminal (PE) is close to 0 V.
• Make sure that the voltage between the drive DC terminals (UDC+ and UDC-)
and the grounding terminal (PE) is close to 0 V.
6. Install temporary grounding as required by the local regulations.
7. Ask for a permit to work from the person in control of the electrical installation
work.

Additional instructions and notes
WARNING! Follow these instructions. If you ignore them, injury or death, or
damage to the equipment can occur.
• If you install the drive on an IT system (an ungrounded power system or a high-
resistance-grounded [over 30 ohms] power system), disconnect the internal EMC
filter; otherwise the system will be connected to ground potential through the EMC
filter capacitors. This can cause danger or damage the drive. See page 76.
Note: Disconnecting the internal EMC filter increases the conducted emission
and reduces the drive EMC compatibility considerably. See section Compliance
with the European EMC Directive on page 134.
• If you install the drive on a corner-grounded TN system, disconnect the internal
EMC filter; otherwise the system will be connected to ground potential through the
EMC filter capacitors. This will damage the drive. See page 159.
Note: Disconnecting the internal EMC filter increases the conducted emission
and reduces the drive EMC compatibility considerably. See section Compliance
with the European EMC Directive on page 134.
• Use all ELV (extra low voltage) circuits connected to the drive only within a zone
of equipotential bonding, that is, within a zone where all simultaneously
accessible conductive parts are electrically connected to prevent hazardous
voltages appearing between them. You can accomplish this by a proper factory
grounding, that is, make sure that all simultaneously accessible conductive parts
are grounded to the protective earth (PE) bus of the building.
• Do not do insulation or voltage withstand tests on the drive or drive modules.
Note:
• The motor cable terminals of the drive are at a dangerous voltage when the input
power is on, regardless of whether the motor is running or not.
• The DC and brake resistor terminals (UDC+, UDC-, R+ and R-) are at a
dangerous voltage.
• External wiring can supply dangerous voltages to the terminals of relay outputs.
• The Safe torque off function does not remove the voltage from the main and
auxiliary circuits. The function is not effective against deliberate sabotage or
misuse.
WARNING! Use a grounding wrist band when you handle the printed circuit
boards. Do not touch the boards unnecessarily. The components on the boards
are sensitive to electrostatic discharge.

Grounding
These instructions are for all personnel who are responsible for the electrical
installation, including the grounding of the drive.
WARNING! Follow these instructions. If you ignore them, injury or death, or
equipment malfunction can occur, and electromagnetic interference can
increase.
• If you are not a qualified electrician, do not do grounding work.
• Always ground the drive, the motor and adjoining equipment to the protective
earth (PE) bus of the power supply. This is necessary for the personnel safety.
Proper grounding also reduces electromagnetic emission and interference.
• In a multiple-drive installation, connect each drive separately to the protective
earth (PE) bus of the power supply.
• Make sure that the conductivity of the protective earth (PE) conductors is
sufficient. See section Selecting the power cables on page 57. Obey the local
regulations.
• Connect the power cable shields to the protective earth (PE) terminals of the
drive.
• Make a 360° grounding of the power and control cable shields at the cable entries
to suppress electromagnetic disturbances.
Note:
• You can use power cable shields as grounding conductors only when their
conductivity is sufficient.
• Standard IEC/EN 61800-5-1 (section 4.3.5.5.2.) requires that as the normal touch
current of the drive is higher than 3.5 mA AC or 10 mA DC, you must use a fixed
protective earth (PE) connection. In addition,
• install a second protective earth conductor of the same cross-sectional area
as the original protective earthing conductor,
or
• install a protective earth conductor with a cross-section of at least 10 mm2Cu
or 16 mm2Al,
or
• install a device which automatically disconnects the supply if the protective
earth conductor breaks.

Additional instructions for permanent magnet motor drives
Safety in installation, start-up and maintenance
These are additional warnings concerning permanent magnet motor drives. The other
safety instructions in this chapter are also valid.
WARNING! Follow these instructions. If you ignore them, injury or death and
damage to the equipment can occur.
• Do not work on a drive when a rotating permanent magnet motor is connected to
it. A rotating permanent magnet motor energizes the drive including its input
power terminals.
Before installation, start-up and maintenance work on the drive:
• Stop the motor.
• Disconnect the motor from the drive with a safety switch or by other means.
• If you cannot disconnect the motor, make sure that the motor cannot rotate during
work. Make sure that no other system, like hydraulic crawling drives, can rotate
the motor directly or through any mechanical connection like felt, nip, rope, etc.
• Measure that the installation is de-energized.
• Use a multimeter with an impedance of at least 1 Mohm.
• Make sure that the voltage between the drive output terminals (T1/U, T2/V,
T3/W) and the grounding (PE) busbar is close to 0 V.
• Make sure that the voltage between the drive input power terminals (L1, L2,
L3) and the grounding (PE) busbar is close to 0 V.
• Make sure that the voltage between the drive DC terminals (UDC+, UDC-) and
the grounding (PE) terminal is close to 0 V.
• Install temporary grounding to the drive output terminals (T1/U, T2/V, T3/W).
Connect the output terminals together as well as to the PE.
Start-up and operation:
• Make sure that the operator cannot run the motor over the rated speed. Motor
overspeed causes overvoltage that can damage or explode the capacitors in the
intermediate circuit of the drive.

Safety instructions 19
General safety in operation
These instructions are for all personnel that operate the drive.
WARNING! Follow these instructions. If you ignore them, injury or death, or
damage to the equipment can occur.
• Do not control the motor with the disconnector at the drive power supply; instead,
use the control panel start and stop keys or commands through the I/O terminals
of the drive.
• Give a stop command to the drive before you reset a fault. If you have an external
source for the start command and the start is on, the drive will start immediately
after the fault reset, unless you configure the drive for pulse start. See the
firmware manual.
• Before you activate automatic fault reset functions of the drive control program,
make sure that no dangerous situations can occur. These functions reset the
drive automatically and continue operation after a fault.
Note: When the control location is not set to Local, the stop key on the control panel
will not stop the drive.
