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! Obey these instructions. If you ignore them, injury or death, or
damage to the equipment can occur.
• Use safety shoes with a metal toe cap to avoid foot injury. Wear protective gloves
and long sleeves. Some parts have sharp edges.
• Handle the drive carefully.
•Lift the drive with a lifting device. Use the lifting eyes of the drive.
•Do not tilt the drive. The drive is heavy and its center of gravity is high. It will
overturn easily.
• Beware of hot surfaces. Some parts, such as heatsinks of power semiconductors,
remain hot for a while after disconnection of the electrical supply.
• Keep the drive in its package or protect it from dust and metal shavings from
drilling and grinding until you install it. Protect the installed drive against dust and
metal shavings. Electrically conductive debris inside the drive can 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. See sections Examining the installation
site on page 40 and Losses, cooling data and noise on page 180 for more
information.
• 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 the automatic fault reset or automatic restart functions of the
drive control program, make sure that no dangerous situations can occur. These
Safety instructions 15
functions reset the drive automatically and continue operation after a fault or
supply break. If these functions are activated, the installation must be clearly
marked as defined in IEC/EN 61800-5-1, subclause 6.5.3, for example, "THIS
MACHINE STARTS AUTOMATICALLY".
• 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.
• Make sure that any safety circuits (for example, emergency stop and Safe torque
off) are validated at start-up. For the Safe torque off, see chapter The Safe torque
off function page 213. For other safety functions, see their separate instructions..
Note:
• If you select an external source for the start command and it is on, the drive will
start immediately after fault reset unless you configure the drive for pulse start.
See the firmware manual.
• Depending on the wiring and parametrization of the drive, the stop key on the
control panel may not stop the drive.
• Only authorized persons are allowed to repair a malfunctioning drive.

Additional instructions and notes
WARNING! Obey these instructions. If you ignore them, injury or death, or
damage to the equipment can occur.
• A drive with EMC filter options +E200 and +E202 connected can be installed to a
symmetrically grounded TN-S system. If you install the drive to another system,
check if you must disconnect the EMC filter. See sections When to disconnect
EMC filter (options E200 and +E202) or ground-to-phase varistor: TN-S, IT,
corner-grounded delta, and midpoint-grounded delta systems on page 79 and
Guidelines for installing the drive to a TT system on page 80.
WARNING! Do not install the drive with EMC filter options +E200 and
+E202 connected to a system that the filter is not suitable for. This can
cause danger, or damage the drive.
Note: When EMC filter +E200 and +E202 is disconnected, the drive EMC
compatibility is considerably reduced.
• A drive with the ground-to-phase varistor connected can be installed to a
symmetrically grounded TN-S system. If you install the drive to another system,
check if you must disconnect the varistor.. See sections When to disconnect EMC
filter (options E200 and +E202) or ground-to-phase varistor: TN-S, IT, cornergrounded delta, and midpoint-grounded delta systems on page 79 and Guidelines
for installing the drive to a TT system on page 80.
WARNING! Do not install the drive with the ground-to-phase varistor
connected to a system that the varistor is not suitable for. If you do, the
varistor circuit can be damaged.
• 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 terminals (UDC+, UDC-) are at a dangerous voltage.
• External wiring can supply dangerous voltages to the terminals of relay outputs
(XRO1, XRO2 and XRO3).
• 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 boards contain
components sensitive to electrostatic discharge.
18 Safety instructions
Grounding
These instructions are for all personnel who are responsible for the electrical
installation, including the grounding of the drive.
WARNING! Obey 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 electrical professional, 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 59. 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 mm
or 16 mm

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! Obey 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 destroy the capacitors in the
intermediate circuit of the drive.
20 Safety instructions
General safety in operation
These instructions are for all personnel that operate the drive.
WARNING! Obey 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.
Additional instruction for DC connection
WARNING! Do not connect the drive DC link to a common DC system. The
drive will get damaged.
