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.
WARNING!
•Only qualified electricians are allowed to install and maintain the drive.
•Never work on the drive, motor cable or motor when main power is applied.
After switching off the 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.Voltage between drive input phases L1, L2 and L3 and the frame is close to
0 V.
2.Voltage between terminals UDC+ and UDC- and the frame is close to 0 V.
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 inside the drive even when the main power on 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.
Note:
The disconnecting device (means) of the drive does not isolate the input cables
•
and busbars from the main AC supply. Before working inside the cabinet,
isolate the input cables and busbars from the main supply with the
disconnecting device at the distribution board or with the disconnector of the
supply transformer.
The motor cable terminals on the drive are at a dangerously high volt ag e whe n
•
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 terminals of relay outputs RO1 to RO3.
The Prevention of Unexpected S t art function does not remove the vo lt age from
•
the main and auxiliary circuits.
Safety Instructions
WARNING!
•Cover the drive when installing to ensure that dust from drilling or foreign
objects do not enter the drive. Electrically conductive dust inside the unit may
cause damage or lead to malfunction.
Ensure sufficient cooling.
•
Welding of the cabinet frame is not recommended. However, if electric welding
•
is the only way to mount the cabinet, follow the instructions given in chapter
"Mechanical Installation". Ensure that welding fumes are not inhaled. If the
welding return wire is connected improperly, the welding circuit may damage
electronic circuits in the cabinet.
When removing the module from the cabinet and manoeuvring it outside the
•
cabinet, prevent it from toppling over by securing it. The drive module is heavy
and has a high center of gravity.

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.
Safety Instructions
8
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.
WARNING!
•Ground the drive, the motor and adjoining equipment to ensure personnel
safety in all circumstances, and to reduce electromagnetic emission and pickup.
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).
Do not install a drive with EMC filter option +E202 on 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 (stated by EN 50178, 5.2.11.1), a fixed protective earth connection is
required.
Fiber Optic Cables
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.).
Safety Instructions
Operation
These warnings are intended for all who plan the operation of the drive or operate
the drive. Ignoring the instructions can cause physical injury or death or damage the
equipment.
WARNING!
•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 of the Standard Application
•
Program 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 the disconnecting device (disconnecting means);
•
instead, use the control panel keys and , or commands via the I/O
board of the drive. The maximum allowed number of charging cycles of the DC
capacitors (i.e. power-ups by applying power) is five in ten minutes.
9
Do not use the optional Prevention of Unexpected Start function for stopping
•
the drive when the drive is running. Give a Stop command instead.
Note:
If an external source for start command is selected and it is ON, the drive (with
•
St andard Application Program) will start immediately after fault reset unle ss the
drive is configured for 3-wire (a pulse) start/stop.
When the control location is not set to Local (L not shown in the status row of
•
the display), the stop key on the control panel will not stop the drive. To stop
the drive using the control panel, press the LOC/REM key and then the stop
key .
Safety Instructions
10
Permanent Magnet Motor
These are additional warnings concerning permanent magnet motor drives.
WARNING! Do not work on the dr ive when the perma nent magnet mo tor is rot ating.
Also, when the supply power is switched off and the inverter is stopped, a rotating
permanent magnet motor feeds power to the intermediate circuit of the drive and the
supply connections become live.
Installation and Maintenance Work
Before installation and maintenance work on the drive:
•Disconnect the motor from the drive with a safety switch
and additionally if possible (or)
•lock the motor shaft and ground the motor connection terminals temporarily by
connecting them together as well as to the PE. Before grounding, measure that
the motor is de-energized.
Operation
Do not run the motor over the rated speed. Motor overspeed leads to overvoltage
which may explode the capacitors in the intermediate circuit of the drive.

protection against limited amounts of falling dirt.
UL Type 1 (ANSI/UL50)
Indoor use primarily to provide protection against contact with the enclosed
equipment and against a limited amount of falling dirt.
Recommendation
NEMA 1 / UL Type 1 enclosures should be applied to clean environments without
circulating dust or other contaminants that may collect on surfaces. Equipment of
this enclosure rating should be applied to clean electrical room or installed in another
enclosure with higher degree of protection. NEMA 1 / UL T ype 1 enclosures typically
are not the best selection for installation on industrial factory floors.
25
NEMA 12 (NEMA Standard 7-15-1991)
Type 12 enclosures are intended for indoor use primarily to provide a degree of
protection against circulating dust, falling dirt, and dripping noncorrosive liquids.

What this Chapter Contains
This chapter contains the instructions that you must follow when selecting the mot or,
cables, protections, cable routing and way of operation for the drive system. Always
follow local regulations.
Note: If the recommendations given by ABB are not followed, the drive may
experience problems that the warranty does not cover.
To Which Products this Chapter Applies
This chapter applies to the ACS800-01/U1, ACS800-02/U2, ACS800-04/U4,
ACS800-PC, and ACS800-07/U7 types up to -0610-X.

Motor Selection and Compatibility
1. Select the motor according to the rating tables in chapter Technical Data. Use the
DriveSize PC tool if the default load cycles are not applicable.
2. Check that the motor ratings lie within the allowed ranges of the drive control
program:
•Motor nominal voltage is 1/2 … 2 · UN of the drive
•Motor nominal current is 1/6 … 2 · I
0 … 2 · I
3. Check that the motor voltage rating meets the application requirements:
•The motor voltage is selected according to the AC voltage feeding the drive when
the drive is equipped with a diode input bridge (a non-regenerative drive) and will
operate in motor mode (i.e. no braking).
•The motor nominal voltage is selected according to “the equivalent AC power
source voltage of the drive” if the intermediate DC circuit voltage of the drive is
increased from the nominal level by resistor braking or by the control program of a
regenerative IGBT line-side converter (parameter selectable function).
The equivalent AC power source voltage for the drive is calculated as follows:

4. Consult the motor manufacturer before using a motor in a drive system where the
motor nominal voltage differs from the AC power source voltage.
5. Ensure that the motor insulation system withstands the maximum peak voltage in the
motor terminals. See the "Requirements Table" below for the required motor
insulation system and drive filtering.
Example: When the supply voltage is 480 V and the drive is operating in motor
mode only, the maximum peak voltage in the motor terminals can be approximated
as follows: 480
V · 1.35 · 2 = 1296 V. Check that the motor insulation system
withstands this voltage.
Protecting the Motor Insulation and Bearings
The output of the drive comprises – regardless of output frequency – pulses of
approximately 1.35 times the equivalent mains network voltage with a very short rise
time. This is the case with all drives employing modern IGBT inverter technology.
The voltage of the pulses can be almost double at the motor terminals, depending on
the attenuation and reflection properties of the motor cable and the terminals. This in
turn can cause additional stress on the motor and motor cable insulation.
Modern variable speed drives with their fast rising voltage pulses and high switching
frequencies can generate current pulses that flow through the motor bearings, which
can gradually erode the bearing races and rolling elements.
The stress on motor insulation can be avoided by using optional ABB du/dt filters.
du/dt filters also reduce bearing currents.
To avoid damage to motor bearings, the cables must be selected and installed
according to the instructions given in the hardware manual. In addition, insulated Nend (non-driven end) bearings and output filters from ABB must be used according
to the following table. Two types of filters are used individually or in combinations:
