Safety Notes
2 Safety Notes
The following basic safety notes must be read carefully to prevent injury to persons and
damage to property. The operator must make sure that the basic safety notes are read
and observed. Make sure that persons responsible for the plant and its operation, as
well as persons who work independently on the unit, have read through the operating
instructions carefully and understood them. If you are unclear about any of the
information in this documentation, or if you require further information, please contact
SEW-EURODRIVE.
2.1 General information
Never install damaged products or take them into operation. Submit a complaint to the
shipping company immediately in the event of damage.
During operation, drive inverters can have live, bare and movable or rotating parts as
well as hot surfaces, depending on their enclosure.
Removing covers without authorization, improper use or incorrect installation and
operation may result in severe injuries to persons or damage to machinery.
Consult the documentation for additional information.
2.2 Target group
Only qualified personnel are authorized to install, start up, repair or service the units
(observe IEC 60364 or CENELEC HD 384 or DIN VDE 0100 and IEC 60664 or DIN
VDE 0110 as well as national accident prevention guidelines).
Qualified personnel in the context of these basic safety notes are: all persons familiar
with installation, assembly, startup and operation of the product who possess the
necessary qualifications.
All persons involved in any other work, such as transportation, storage, operation and
disposal, must have suitable training.
2.3 Designated use
Drive inverters are components intended for installation in electrical systems or
machines.
In case of installation in machines, startup of the drive inverters (i.e. start of designated
operation) is prohibited until it is determined that the machine meets the requirements
stipulated in the EC Directive 98/37/ EC (machine guideline); observe EN 60204.
Startup (i.e. start of designated operation) is only permitted with adherence to
EMC (89/336/EEC) guideline.
The drive inverters meet the requirements stipulated in low voltage guideline
73/23/EEC. The harmonized standards of the EN 61800-5-1/DIN VDE T105 series in
connection with EN 60439-1/VDE 0660 part 500 and EN 60146/VDE 0558 are applied
to these drive inverters.
Technical data and information on the connection requirements are given on the
nameplate and in the documentation; they have to be observed under all circumstances.
Safety functions The MOVIDRIVE®compact drive inverters may not perform safety functions without
higher-level safety systems. Use higher-level safety systems to ensure protection of
personnel and equipment.

Transportation, putting into storage
Safety Notes
2.4 Transportation, putting into storage
Observe the notes on transportation, storage and proper handling. Observe the climatic
conditions as stated in the section "General technical data."
2.5 Installation
Installation and cooling of the devices must take place according to the guidelines listed
in the corresponding documentation.
Protect the drive inverters from excessive strain. Especially during transportation and
handling, do not allow the components to be deformed or insulation spaces altered.
Avoid contact with electronic components and contacts.
Drive inverters contain components that can be damaged by electrostatic energy and
improper handling. Prevent mechanical damage or destruction of electric components
(may pose health risk!)
The following applications are prohibited unless measures are expressly taken to make
them possible:
• Use in potentially explosive atmospheres
• Use in areas exposed to harmful oils, acids, gases, vapors, dust, radiation, etc.
• Use in non-stationary applications that are subject to mechanical vibration and shock
loads in excess of the requirements in EN 50178
2.6 Electrical connection
Observe the applicable national accident prevention guidelines when working on live
drive inverters (e.g. BGV A3).
Perform electrical installation according to the pertinent regulations (e.g. line cross
sections, fusing, protective conductor connection). For any additional information, refer
to the applicable documentation.
You will find notes on EMC-compliant installation, such as shielding, grounding,
arrangement of filters and routing of lines, in the documentation of the drive inverters.
Always observe these notes even with drive inverters bearing the CE marking. The
manufacturer of the system or machine is responsible for maintaining the limits
established by the EMC legislation.
Preventive measures and protection devices must correspond to the regulations in force
(e.g. EN 60204 or EN 61800-5-1).
Required preventive measures: Ground the unit.
2.7 Safe disconnection
The unit meets all requirements for safe disconnection of power and electronic
connections in accordance with EN 61800-5-1. All connected circuits must also satisfy
the requirements for safe disconnection.

2Operation
Safety Notes
2.8 Operation
Systems with integrated drive inverters must be equipped with additional monitoring and
protection devices, if necessary, according to the applicable safety guidelines, such as
the law governing technical equipment, accident prevention regulations, etc. Changes
to the drive inverter using the operating software are permitted.
Do not touch live components or power connections immediately after disconnecting the
drive inverters from the supply voltage because there may still be some charged
capacitors. Note the respective reference plates on the drive inverter.
Keep all covers and doors closed during operation.
The fact that the status LED and other display elements are no longer illuminated does
not indicate that the unit has been disconnected from the power supply and no longer
carries any voltage.
Mechanical blocking or internal safety functions of the unit can cause a motor standstill.
Removing the cause of the problem or performing a reset can result in the drive re-
starting on its own. If, for safety reasons, this is not permitted for the driven machine,
disconnect the unit from the mains before correcting the fault.

cross section of the supply system lead parallel to the protective earth via
separate terminals or use a copper protective earth conductor with a cross
section of 10 mm2.
•Forasupply system lead 10 mm2... 16 mm2: Route a copper protective earth
conductor with the cross section of the power supply line.
•Forasupply system lead 16 mm2... 35 mm2: Route a copper protective earth
conductor with the cross section of 16 mm2.
•Forasupply system lead > 35 mm2: Route a copper protective earth conductor
with half the cross section of the power supply line.
IT systems • SEW-EURODRIVE recommends using earth-leakage monitors with pulse-code
measurement for voltage supply systems with a non-grounded star point
(IT systems). Using such devices prevents the earth-leakage monitor mis-tripping
due to the ground capacitance of the inverter. No EMC limits are specified for
interference emission in voltage supply systems without grounded star point
(IT systems).
WARNING!
Incorrect earth-leakage circuit breaker installed.
Severe or fatal injuries.
MOVIDRIVE®can cause direct current in the protective earth. In cases where an earth-
leakage circuit breaker is used for protection against direct or indirect contact, only
install a type B earth-leakage circuit breaker on the power supply end of the
MOVIDRIVE®unit.
NOTES
• Only use the mains contactor K11 (→Sec. "Wiring diagram for basic unit") to
switch the inverter on and off. Do not use it for jog mode. Use the commands
"Enable/Stop", "CW/Stop" or "CCW/Stop" for jog mode.
• Observe a minimum switch-off time of 10 s for the input contactor K11.

Installation
Cross sections • Supply system lead: Cross section according to rated input current Imains at rated
load.
• Motor lead: Cross section according to rated output current Irated.
• Electronics cables for MCH:
– Only single cores 0.20...1.5 mm2(AWG 24...12)
– Use right-angled crimping pliers with 1.5 mm2(AWG 16)
Unit output
Connecting
braking resistors
• Use two tightly twisted leads or a 2-core shielded power cable. Cross section
according to the rated output current of the inverter.
• Protect the braking resistor with a bimetallic relay / thermal overload relay
(→Wiring diagram for basic unit, power section and brake). Set the trip current
according to the technical data of the braking resistor. SEW-EURODRIVE
recommends using an overcurrent relay of trip class 10 or 10A in accordance with
EN 60947-4-1.
• For braking resistors of the BW...-T / BW...-P series, the integrated temperature
switch/overcurrent relay can be connected using a 2-core shielded cable as an
alternative to a bimetallic relay.
• Install the flat-type braking resistors together with the appropriate touch guard.

Installation instructions for the basic unit
Installation
Operating
braking resistors
• The connection leads to the braking resistors carry a high pulsed DC voltage during
rated operation.
Binary inputs /
binary outputs
• The binary inputs are electrically isolated by optocouplers.
• The binary outputs are short-circuit proof and protected against external
voltage to DC 30 V. External voltages > DC 30 V can cause irreparable damage to
binary outputs.
EMC compliant
installation
• Only use shielded control cables.
• All cables except for the supply system lead must be shielded. As an alternative to
shielding, the HD.. output choke option can be used for the motor cable to achieve
the emitted interference limit values.
• When using shielded motor cables, e.g. prefabricated motor cables from
SEW-EURODRIVE, you must keep the unshielded conductors between the
shield and connection terminal of the inverter as short as possible.
• Apply the shield by the shortest possible route and make sure it is grounded
over a wide area at both ends. Ground one end of the shield via a suppression
capacitor (220 nF / 50 V) to avoid ground loops. If using double-shielded cables,
ground the outer shield on the controller end and the inner shield on the other end.
• You can also use grounded sheet-metal ducts or metal pipes to shield the
cables. Route the power and control cables separately.
• Provide high frequency compatible grounding for the inverter and all additional
units (wide area metal-on-metal contact between the unit housing and ground, e.g.
unpainted control cabinet mounting panel).
WARNING!
The surfaces of the braking resistors get very hot when the braking resistors are loaded
with Prated.
Risk of burns and fire.
• Choose a suitable installation location. Braking resistors are usually installed on top
of the control cabinet.
• Do not touch the braking resistors.
