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.

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: 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 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 19

• 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.
