Safety instructions
What this chapter contains
This chapter contains the safety instructions you must follow when installing, operating and servicing
the drive/unit.
If ignored, physical injury or death may follow, or damage may occur to the drive/unit, the motor/load or
driven equipment. Read the safety instructions before you work on the unit.
To which products this chapter applies
The information is valid for the whole range of the product line DCS880, the converter modules DCS880-
S0x size H1 … H8, field exciter units DCF80x, Rebuild Kit DCS880-R00, etc.
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 advice 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 voltage which can cause physical injury or death
and/or damage to the equipment.
General danger warning warns about conditions, other than those caused by electricity,
which can result in physical injury or death and/or damage to the equipment.
Electrostatic sensitive devices 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/unit, motor/load cable or motor/load.
Ignoring the instructions can cause physical injury or death and/or damage to the equipment.
WARNING
−Only qualified electricians are allowed to install and maintain the drive/unit!
−Never work on the drive/unit, motor/load cable or motor/load when mains power is
applied.
−Always ensure by measuring with a multimeter (impedance at least 1 MΩ) that:
−1. Voltage between drive/unit input phases U1, V1 and W1 and the frame is close
to 0 V.
−2. Voltage between terminals C+ and D- and the frame is close to 0 V.
−Do not work on the control cables when power is applied to the drive/unit or to the
external control circuits. Externally supplied control circuits may cause dangerous
voltages inside the drive/unit even when the mains
power on the drive/unit is switched
off.
−Do not make any insulation resistance or voltage withstand tests on the drive/unit or
drive modules.
−Isolate the motor/load cables from the drive/unit when testing the insulation
resistance or voltage withstand of the cables or the motor/load.
−When reconnecting the motor/load cable, always check that the C+ and D- cables are
connected with the proper terminal.

Safety instructions
3ADW000803R0101 DCS880 H4T (Tosa) manual en a
Notes:
−The motor/load cable terminals on the drive/unit are at a dangerously high voltage
when the mains power is on, regardless of whether the motor/load is running or not.
−Depending on the external wiring, dangerous voltages (115 V, 220 V or 230 V) may be
present on the relay outputs of the drive/unit system (e.g. XRO1 … XRO3).
−DCS880 with enclosure extension: Before working on the drive/unit, isolate the whole
drive/unit system from the supply.
Grounding
These instructions are intended for all who are responsible for the grounding of the drive/unit. Incorrect
grounding can cause physical injury, death and/or equipment malfunction and increase electromagnetic
interference.
WARNING
−Ground the drive/unit, motor/load 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 and marked as required by
safety regulations.
−In a multiple-drive/unit installation, connect each drive/unit separately to protective
earth (PE ).
−Minimize EMC emission and make a 360° high frequency grounding (e.g. conductive
sleeves) of screened cable entries at the cabinet lead-through plate.
−Do not install a drive/unit equipped with an EMC filter to an ungr
ounded power system or
a high resistance-grounded (> 30 Ω) power system.
Notes:
−Power cable shields are suitable as equipment grounding conductors only when
adequately sized to meet safety regulations.
−As the normal leakage current of the drive/unit is higher than 3.5 mAAC or 10 mADC a fixed
protective earth connection is required.
−This product can cause a DC current in the protective earthing conductor. Where a
residual current-operated protective (RCD) or monitoring (RCM) device is used for
protection in case of direct or indirect contact, only an RCD or RCM of Type B is allowed
on the supply side of this product.
Printed circuit boards and fiber optic cables
These instructions are intended for all who handle the circuit boards and fiber optic cables. Ignoring the
following instructions can cause damage to the equipment.
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.
−Use grounding strip:
−
ABB order no.: 3ADV050035P0001
WARNING
−Handle the fiber optic cables with care.
−When unplugging optic cables, always grab the connector, not the cable itself.

Safety instructions
3ADW000803R0101 DCS880 H4T (Tosa) manual en a
−Do not touch the ends of the fibers with bare hands as the fiber is extremely sensitive
to dirt.
−The minimum allowed bend radius is 35 mm (1.38 in.).
Mechanical installation
These notes are intended for all who install the drive/unit. Handle the unit carefully to avoid damage and
injury.
WARNING
−DCS880 sizes H4 ... H8:
−The drive/unit is heavy. Lift the drive/unit by lifting lugs only.
−The drive’s/unit’s center of gravity is high. Do not tilt the drive/unit. The
drive/unit will overturn from a tilt of about 6 degrees. An overturning drive/unit
can cause physical injury.
−Do not lift the drive/unit by the front cover.
−Place drives/units H4 … H6 only on their back.
−Make sure that dust from drilling does not enter the drive/unit when installing.
Electrically conductive dust inside the drive/unit may cause damage or lead to
malfunction.
−Ensure sufficient cooling.
−Do not fasten the drive/unit by riveting or welding.
Operation
These warnings are intended for all who plan the operation of the drive/unit or operate the drive/unit.
Ignoring the instructions can cause physical injury or death and/or damage to the equipment.
WARNING
−Before adjusting the drive/unit and putting it into service, make sure that the
motor/load and all driven equipment are suitable for operation throughout the
speed/voltage range provided by the drive/unit. The drive can be adjusted to operate
the motor at speeds above and below the base speed.
−Do not control the motor/load with the disconnecting device (disconnecting mains);
instead, use the control panel keys and
, or commands via the I/O board of the
drive/unit.
−Mains connection:
You can use a disconnect switch (with fuses) to disconnect the electrical components
of the drive/unit from the mains for installation and maintenance work. The type of
disconnect switch used must be as per EN 60947-3, Class B, so as to comply with EU
regulations, or a circuit-breaker type which switches off the load circuit by means of an
auxiliary contact causing the breaker's main contacts to open. The mains disconnect
must be locked in its "OPEN" position during any installation and maintenance work.
−EMERGENCY STOP buttons must be installed at each control desk and at all other
control panels requiring an emergency stop function. Pressing the STOP button on the
control panel of the drive/unit will neither cause an emergency stop of the motor/load,
nor will the drive/unit be disconnected from any dangerous potential.
−To avoid unintentional operating states, or to shut the unit down in case of any
imminent danger according to the standards in the safety instructions it is not
sufficient to merely shut down the drive/unit via signals "RUN", "drive/unit OFF" or
"Emergency Stop" respectively "control panel" or "PC tool".
−Intended use:
The operating instructions cannot take into consideration every possible case of
configuration, operation or maintenance. Thus, they mainly give such advice only,

which is required by qualified personnel for normal operation of the machines and
devices in industrial installations.
If in special cases the electrical machines and devices are intended for use in non-
industrial installations - which may require stricter safety regulations (e.g. protection
against contact by children or similar) - these additional safety measures for the
installation must be provided by the customer during assembly.
Note:
−When the control location is not set to Local (Local not shown in the status row of the
display), the stop key on the control panel will not stop the drive/unit. To stop the
drive/unit using the control panel, press the Loc/Rem key and then the stop key .

2-Q units size H4T
To increase the mains voltage and DC voltage of some DCS880 2-Q units size H4 the SDCS-PIN-H01 has
been substituted by an SDCS-POW-H01 together with an SDCS-PIN-H51 and an SDCS-PIN-H41. This
creates DCS880 2-Q units size H4T.

Galvanic isolation - T90, A92, F11, F90
The Galvanic isolation is an option for converters size H4T, H6 ... H8 and rated voltages ≤ 1000 V.
It is used to replace the high-ohmic voltage measurement and gives the advantage of a total isolation
between power part and drive electronics.
The transformer T90 and the DC-DC transducer A92 are located outside the converter module. The
internal AC and DC voltage measurement channels are removed and connected to T90 and A92.
