Safety instructions
What this chapter contains
This chapter contains safety instructions which you must follow when installing,
operating and servicing the drive. If ignored, physical injury or death may follow, or
damage may occur to the drive, the motor, or driven equipment. Read the safety
instructions before you work on the unit.
Use of warnings and notes
There are four types of safety instructions used in this manual:
Electricity warning warns of high voltage which can cause physical
injury and/or damage to the equipment.
General warning warns about conditions, other than those caused by
electricity, which can result in physical injury and/or damage to the
equipment.
Electrostatic discharge warning warns of electrostatic discharge which
can damage the equipment.
Hot surface warning warns of component surfaces that may become
hot enough to cause burns if touched.

Safety instructions

Installation and maintenance work
These warnings are intended for all who work on the drive, motor cable or motor.
WARNING! Ignoring the following instructions can cause physical injury or death, or
damage to the equipment.
Only qualified electricians are allowed to install and maintain the drive.
•Never work on the drive, the motor cable or the motor when input power is
applied. After disconnecting the input power, always wait for 5 minutes to let the
intermediate circuit capacitors discharge before you start working on the drive,
the motor or the motor cable.
Always ensure by measuring with a multimeter (impedance at least 1 Mohm)
that:
1. There is no voltage between the drive input phases U1, V1 and W1 and the
ground.
2. There is no voltage between terminals UDC+ and UDC– and the ground.
3. There is no voltage between terminals R+ and R– and the ground.
•Drives controlling a permanent magnet motor: A rotating permanent magnet
motor feeds power to the drive causing the drive to become live even when it is
stopped and the supply power switched off. Before maintenance work on the
drive,
– disconnect the motor from the drive by using a safety switch
– prevent the start-up of any other motors in the same mechanical system
– lock the motor shaft
– measure that the motor is in fact de-energised, then connect the U2, V2 and
W2 terminals of the drive to each other and to the PE.
•Do not work on the control cables when power is applied to the drive or to the
external control circuits. Externally supplied control circuits may carry
dangerous voltages even when the input power of the drive is switched off.
•Do not make any insulation or voltage withstand tests on the drive.
•If a drive whose varistors or internal EMC filters are not disconnected is
installed on an IT power system (an ungrounded power system or a high
resistance grounded [over 30 ohms] power system), the drive will be connected
to earth potential through the varistors/filters. This may cause danger or
damage the drive.
•If a drive whose varistors or internal EMC filter are not disconnected is installed
on a corner-grounded TN system, the drive will be damaged.
Notes:
•Even when the motor is stopped, dangerous voltages are present at the power
circuit terminals U1, V1, W1 and U2, V2, W2, and UDC+, UDC–, R+, R–.

•Depending on the external wiring, dangerous voltages (115 V, 220 V or 230 V)
may be present on the terminals of the relay outputs of the drive.
•The drive supports the “Safe Torque Off” function. See page 42.
WARNING! Ignoring the following instructions can cause physical injury or death, or
damage to the equipment.
•The drive is not field repairable. Never attempt to repair a malfunctioning drive;
contact your local ABB representative or Authorized Service Center for
replacement.
•Make sure that dust from drilling does not enter the drive during the installation.
Electrically conductive dust inside the drive may cause damage or lead to
malfunction.
•Ensure sufficient cooling.
WARNING! The printed circuit boards contain components sensitive to electrostatic
discharge. Wear a grounding wrist band when handling the boards. Do not touch
the boards unnecessarily.

Start-up and operation
These warnings are intended for all who plan the operation of the drive, start up or
operate the drive.
WARNING! Ignoring the following instructions can cause physical injury or death,
or damage to the equipment.
•Before adjusting the drive and putting it into service, make sure that the motor
and all driven equipment are suitable for operation throughout the speed range
provided by the drive. The drive can be adjusted to operate the motor at
speeds above and below the speed provided by connecting the motor directly
to the power line.
•Do not activate automatic fault reset functions if dangerous situations can
occur. When activated, these functions will reset the drive and resume
operation after a fault.
•Do not control the motor with an AC contactor or disconnecting device
(disconnecting means); instead, use the control panel or external commands
via the I/O board of the drive or a fieldbus adapter. The maximum allowed
number of charging cycles of the DC capacitors (i.e. power-ups by applying
power) is one per two minutes. The maximum total number of chargings is
100000 for frame sizes A and B, 50000 for frame sizes C and D.
•Drives controlling a permanent magnet motor: Do not run the motor over the
rated speed. Motor overspeed leads to overvoltage which may permanently
damage the drive.
Notes:
•If an external source for start command is selected and it is ON, the drive will
start immediately after an input voltage break or a fault reset unless the drive is
configured for 3-wire (pulse) start/stop.
•When the control location is not set to local, the stop key on the control panel
will not stop the drive.
WARNING! The surfaces of drive system components (such as the mains choke
and braking resistor, if present) become hot when the system is in use.
