Safety instructions
What this chapter contains
This chapter contains safety instructions 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.
Usage of warnings and notes
There are two types of safety instructions throughout this manual: warnings and
notes. Warnings caution you about conditions which can result in serious injury or
death and/or damage to the equipment, and advise on how to avoid the danger.
Notes draw attention to a particular condition or fact, or give information on a
subject. The warning symbols are used as follows:
Dangerous voltage warning warns of high voltages 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.

Installation and maintenance work
These warnings are intended for all who work on the drive, motor cable or motor.
Ignoring the instructions can cause physical injury or death, or damage the
equipment.
WARNING!
•Only qualified electricians are allowed to install and maintain the drive.
•The main switch on the cabinet door does not remove the voltage from the input
busbars of the drive. Before working on the drive, isolate the whole drive from
the supply.
•Never work on the drive, the motor cable or the motor when main power is
applied. After switching off the input power, always wait for 5 min to let the
intermediate circuit capacitors discharge before you start working on the drive,
the motor or the motor cable. Measure the voltage between terminals UDC+
and UDC- (L+ and L–) with a multimeter (impedance at least 1 Mohm) to
ensure that the drive is discharged before beginning work.
•Apply temporary grounding before working on the unit.
•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 cause
dangerous voltages to exist inside the drive even when the main power of the
drive is switched off.
•Do not make any insulation or voltage withstand tests on the drive or drive
modules.
•When reconnecting the motor cable, always check that the phase order is
correct.
•When joining shipping splits (if any), check the cable connections at the joints
before switching on the supply voltage.
•Live parts on the inside of the doors are protected against direct contact.
Special attention shall be paid when handling metallic shrouds.
•After maintaining or modifying a drive safety circuit or changing circuit boards
inside the module, retest the functioning of the safety circuit according to the
start-up instructions.
•Do not change the electrical installations of the drive except for the essential
control and power connections. Changes may affect the safety performance or
operation of the drive unexpectedly. All customer-made changes are on the
customer's responsibility.
Note:
•The motor cable terminals on the drive are at a dangerously high voltage when
the input power is on, regardless of whether the motor is running or not.

•The brake control terminals (UDC+, UDC-, R+ and R- terminals) carry a
dangerous DC voltage (over 500 V).
•Depending on the external wiring, dangerous voltages (115 V, 220 V or 230 V)
may be present on the relay outputs of the drive system.
•The Prevention of unexpected start-up function (option +Q950) does not
remove the voltage from the main and auxiliary circuits.
•The Safe torque off function (option +Q968) does not remove the voltage from
the main and auxiliary circuits.

WARNING! Ignoring the following instructions can cause physical injury or death, or
damage to the equipment.
•Use extreme caution when manoeuvring an inverter, supply or filter module that
runs on wheels. The modules are heavy and have a high centre of gravity. They
topple over easily if handled carelessly.
•Do not use the ramp which is supplied with the drive with heights over 50 mm
(the standard plinth height of ABB cabinets). The ramp is designed for a plinth
height of 50 mm.
Do not tilt!Support the top and
bottom of the module
while removing!
Lift the module by the upper part only
using the lifting hole(s) at the top!
Extend the support legs outside the
cabinet!
Mind your fingers! Keep fingers away from the
edges of the front flange of the module!
Support the top and bottom
of the module while
replacing!

Grounding
These instructions are intended for all who are responsible for the grounding of the
drive. Incorrect grounding can cause physical injury, death or equipment malfunction
and increase electromagnetic interference.
•When removing a module which is equipped with wheels, pull the module
carefully out of the cubicle along the ramp. Make sure that the wires do not
catch. While pulling on the handle, keep a constant pressure with one foot on
the base of the module to prevent the module from falling on its back.
•When replacing a module which is equipped with wheels, push the module up
the ramp and back into the cubicle. Keep your fingers away from the edge of
the module front plate to avoid pinching them between the module and the
cubicle. Also, keep a constant pressure with one foot on the base of the module
to prevent the module from falling on its back.
•Electrically conductive dust inside the unit may cause damage or lead to
malfunction. Make sure that dust from drilling does not enter the drive when
installing.
•Fastening the cabinet by riveting or welding is not recommended. However, if
welding is necessary, ensure the return wire is properly connected in order not
to damage the electronic equipment in the cabinet. Also ensure that welding
fumes are not inhaled.
•Ensure sufficient cooling of the unit.
•Cooling fans may continue to rotate for a while after the disconnection of the
electrical supply.
•Some parts inside the drive cabinet, such as heatsinks of power
semiconductors, remain hot for a while after the disconnection of the electrical
supply.
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.
WARNING!
•Ground the drive, the motor and adjoining equipment to ensure personnel
safety in all circumstances, and to reduce electromagnetic emission and pick-
up.
•Make sure that grounding conductors are adequately sized as required by
safety regulations.
•In a multiple-drive installation, connect each drive separately to protective
earth (PE).

Fibre optic cables
•Do not install a drive equipped with an EMC (line) filter to an ungrounded
power system or a high resistance-grounded (over 30 ohms) power system.
Note:
•Power cable shields are suitable for equipment grounding conductors only
when adequately sized to meet safety regulations.
•As the normal leakage current of the drive is higher than 3.5 mA AC or
10 mA DC, a fixed protective earth connection is required by EN 61800-5-1,
4.3.5.5.2. The cross-section of the protective grounding conductor must be at
least 10 mm2 Cu or 16 mm2 Al.
WARNING!
•Handle the fibre optic cables with care. When unplugging optic cables, always
grab the connector, not the cable itself. Do not touch the ends of the fibres with
bare hands as the fibre is extremely sensitive to dirt. The minimum allowed
bend radius is 35 mm (1.4 in.).
