Safety instructions
Contents of this chapter
This chapter contains the safety instructions which you must obey when you install, start
up, operate and do maintenance work on the drive. If you ignore the safety instructions,
injury, death or damage can occur.
Use of warnings and notes
Warnings tell you about conditions which can cause injury or death, or damage to the
equipment. They also tell you how to prevent the danger. Notes draw attention to a particular
condition or fact, or give information on a subject.
The manual uses these warning symbols:
WARNING!
Electricity warning tells about hazards from electricity which can cause injury or
death, or damage to the equipment.
WARNING!
General warning tells about conditions, other than those caused by electricity,
which can cause injury or death, or damage to the equipment.
WARNING!
Electrostatic sensitive devices warning tells you about the risk of electrostatic
discharge which can cause damage to the equipment.

Safety instructions 15

General safety in installation, start-up and maintenance
These instructions are for all personnel who do work on the drive.
WARNING!
Obey these instructions. If you ignore them, injury or death, or damage to the
equipment can occur.
• Keep the drive in its package until you install it. After unpacking, protect the drive from
dust, debris and moisture.
•Use the required personal protective equipment: safety shoes with metal toe cap, safety
glasses, protective gloves and long sleeves, etc. Some parts have sharp edges.
•Lift a heavy drive with a lifting device. Use the designated lifting points. See the dimension
drawings.
• Incorrect lifting can cause danger or damage. Obey the local laws and regulations
applicable to lifting, such as requirements for planning the lift, for capacity and condition
of lifting equipment, and for training of personnel.
• Attach the drive cabinet to the floor to prevent it from toppling over. The cabinet has a
high center of gravity. When you pull out heavy components or power modules, there
is a risk of overturning. Attach the cabinet also to the wall when necessary.
• Do not use the module extraction/installation ramp with plinth heights which exceeds
the maximum allowed height. See the technical data.
• Attach the module extraction/installation ramp carefully.

• Make sure that the module does not topple over when you move it on the floor: Open
the support legs by pressing each leg a little down (1, 2) and turning it aside. Whenever
possible attach the module also with chains. Do not tilt the drive module. It is heavy and
its center of gravity is high. The module overturns from a sideways tilt of 5 degrees. Do
not leave the module unattended on a sloping floor.

• To prevent the drive module from falling, attach its top lifting lugs with chains to the
cabinet (1) before you push the module into the cabinet and pull it from the cabinet.
Push the module into the cabinet and pull it from the cabinet carefully preferably with
help from another person. Keep a constant pressure with one foot on the base of the
module (2) to prevent the module from falling on its back.

• Beware of hot surfaces. Some parts, such as heatsinks of power semiconductors, and
brake resistors, remain hot for a while after disconnection of the electrical supply.
Safety instructions 17

• Vacuum clean the area around the drive before the start-up to prevent the drive cooling
fan from drawing the dust inside the drive.
• Make sure that debris from drilling, cutting and grinding does not enter the drive during
the installation. Electrically conductive debris inside the drive may cause damage or
malfunction.
• Make sure that there is sufficient cooling. See the technical data.
• Keep the cabinet doors closed when the drive is powered. With the doors open, a risk
of a potentially fatal electric shock, arc flash or high-energy arc blast exists. If you cannot
avoid working on a powered drive, obey the local laws and regulations on live working
(including – but not limited to – electric shock and arc protection).
• 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 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 drive power cycles is five times in ten minutes. Power cycling the drive
too often can damage the charging circuit of the DC capacitors.
• If you have connected safety circuits to the drive (for example, Safe torque off or
emergency stop), validate them at start-up. See separate instructions for the safety
circuits.
• Beware of hot air exiting from the air outlets.
• Do not cover the air inlet or outlet when the drive is running.
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.
• If the drive is in remote control mode, you cannot stop or start the drive with the control
panel.
• Only authorized persons are allowed to repair a malfunctioning drive.

WARNING!
Obey these instructions. If you ignore them, injury or death, or damage to the
equipment can occur.
If you are not a qualified electrical professional, do not do installation or
maintenance work.
Go through these steps before you begin any installation or maintenance work.
1. Clearly identify the work location and equipment.
2. Disconnect all possible voltage sources. Make sure that re-connection is not possible.
Lock out and tag out.
• Open the main disconnecting device of the drive.
• Open the charging switch if present.
• Open the disconnector of the supply transformer. (The main disconnecting device
in the drive cabinet does not disconnect the voltage from the AC input power busbars
of the drive cabinet.)
• Open the auxiliary voltage switch-disconnector (if present), and all other possible
disconnecting devices that isolate the drive from dangerous voltage sources.
•If you have a permanent magnet motor connected to the drive, disconnect the motor
from the drive with a safety switch or by other means.
• Disconnect all dangerous external voltages from the control circuits.
• After you disconnect power from the drive, always wait 5 minutes to let the
intermediate circuit capacitors discharge before you continue.
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. If the measurement requires removal or
disassembly of shrouding or other cabinet structures, obey the local laws and regulations
applicable to live working (including – but not limited to – electric shock and arc
protection).
• Before and after measuring the installation, verify the operation of the voltage tester
on a known voltage source.
• Make sure that the voltage between the drive input power terminals (L1, L2, L3)
and the grounding (PE) busbar is zero.
• Make sure that the voltage between the drive output terminals (T1/U, T2/V, T3/W)
and the grounding (PE) busbar is zero.
• Make sure that the voltage between the drive DC terminals (R+/UDC+ and UDC-)
and the grounding (PE) terminal is zero.
6. Install temporary grounding as required by the local regulations.
7. Ask the person in control of the electrical installation work for a permit to work.
￭Additional instructions and notes
WARNING!
Obey these instructions. If you ignore them, injury or death, or damage to the
equipment can occur.
If you are not a qualified electrical professional, do not do installation or
maintenance work.
Safety instructions 19

• Keep the cabinet doors closed when the drive is powered. With the doors open, a risk
of a potentially fatal electric shock, arc flash or high-energy arc blast exists.
• Make sure that the electrical power network, motor/generator, and environmental
conditions agree with the drive data.
• Do not do insulation or voltage withstand tests on the drive.
• If you have a cardiac pacemaker or other electronic medical device, keep away from
the area near motor, drive, and the drive power cabling when the drive is in operation.
There are electromagnetic fields present which can interfere with the function of such
devices. This can cause a health hazard.
• Remove the code labels attached to mechanical parts such as busbars, shrouds and
sheet metal parts before installation. They may cause bad electrical connections, or,
after peeling off and collecting dust in time, cause arcing or block the cooling air flow.
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.
• When the input power is on, the drive DC bus is at a dangerous voltage.
• External wiring can supply dangerous voltages to the relay outputs of the control units
of the drive.
• 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.
Optical components
WARNING!
Obey these instructions. If you ignore them, damage to the equipment can occur.
• Handle the fiber optic cables with care.
• When you unplug the fiber optic cables, always hold the connector, not the cable itself.
• Do not touch the ends of the fibers with bare hands as the ends are extremely sensitive
to dirt.
• Do not bend the fiber optic cables too tightly. The minimum allowed bend radius is
35 mm (1.4 in).
Printed circuit boards
WARNING!
Use a grounding wrist band when you handle printed circuit boards. Do not touch
the boards unnecessarily. The boards contain components sensitive to electrostatic
discharge.
￭Grounding
These instructions are for all personnel who are responsible for 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.
