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.
• Attach the module extraction/installation ramp carefully.
• Make sure that the module does not topple over when you move it on the floor:
To open the support legs, press each leg a little down and turn it aside (1, 2).
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 when tilted more
than 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.
• Vacuum clean the area around the drive before the start-up to prevent the drive
cooling fan from drawing dust inside the drive.
Safety instructions 17

• Make sure that debris from drilling, cutting and grinding does not go into the
drive during installation. Electrically conductive debris inside the drive can 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/UL 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.
• 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.

Electrical safety in installation, start-up and maintenance
￭Electrical safety precautions
These electrical safety precautions are for all personnel who do work on the drive,
motor cable or motor.
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.
Do 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. Use a quality voltage tester. 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.
Important! Repeat the measurement also with the DC voltage setting of the
tester. Measure between each phase and ground. There is a risk of dangerous
DC voltage charging due to leakage capacitances of the motor circuit. This
voltage can remain charged for a long time after the drive power-off. The
measurement discharges the voltage.
• Make sure that the voltage between the drive DC terminals (UDC+ and UDC-)
and the grounding (PE) terminal is zero.

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!
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.
• 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:
• When the drive is connected to the input power, the motor cable terminals and
the DC bus are at a dangerous voltage.
The brake circuit, including the brake chopper (option +D150) and brake resistor
(if installed) are also at a dangerous voltage.
After disconnecting the drive from the input power, these remain at a dangerous
voltage until the intermediate circuit capacitors have discharged.
• 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.
Printed circuit boards
WARNING!
Use a grounding wristband when you handle printed circuit boards. Do not
touch the boards unnecessarily. The boards contain components sensitive to
electrostatic discharge.
