Safety Notes
2.3.1 Safety functions
Field distributors, fieldbus interfaces and MOVIMOT®inverters may not perform safety
functions unless these functions are described and expressly permitted.
If MOVIMOT®inverters are used in safe applications, you must observe the supplemen-
tal documentation "MOVIMOT®– Functional Safety". Use only those components in
safety applications that were explicitly designed and delivered for this purpose by SEW-
EURODRIVE.
2.3.2 Hoist applications
When using MOVIMOT®inverters in hoist applications, you must observe the special
configuration and settings for hoist applications specified in the operating instructions for
MOVIMOT®.
MOVIMOT®inverters are not designed for use as a safety device in hoist applications.
2.4 Transportation, storage
You must observe the notes on transportation, storage and proper handling. Comply
with the requirements for climatic conditions stated in chapter "Technical Data" of the
operating instructions. Tighten installed eyebolts securely. They are designed for the
weight of the MOVIMOT®drive. Do not attach any additional loads. Use suitable,
sufficiently rated handling equipment (e.g. rope guides) if required.
2.5 Installation
The units must be installed and cooled according to the regulations and specifications
in the corresponding documentation.
Protect the MOVIMOT®inverters from improper strain.
The following applications are prohibited unless the unit is explicitly designed for such
use:
• Use in potentially explosive atmospheres.
• Use in areas exposed to harmful oils, acids, gases, vapors, dust, radiation, etc.
• Use in non-stationary applications with strong mechanical oscillation and impact
loads, as specified in the documentation
2.6 Electrical connection
Observe the applicable national accident prevention guidelines when working on live
MOVIMOT®drive inverters (e.g. BGV A3).
Perform electrical installation according to the pertinent regulations (e.g. cable cross
sections, fusing, protective conductor connection). For any additional information, refer
to the applicable documentation.
For information on EMC-compliant installation – such as shielding, grounding,
arrangement of filters and routing of lines – refer to the documentation. The manufac-
turer of the system or machine is responsible for maintaining the limits established by
EMC legislation.
Protective measures and protection devices must comply with the regulations in force
(e.g. EN 60204 or EN 61800-5-1).

Safe disconnection
Safety Notes
A voltage test according to EN 61800-5-1:2007 chapter 5.2.3.2 is required for
MOVIMOT®drives prior to startup to ensure insulation.
2.7 Safe disconnection
MOVIMOT®inverters meet 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.
2.8 Operation
Systems with integrated MOVIMOT®inverters must be equipped with additional
monitoring and protection devices according to the applicable safety guidelines, such as
the law governing technical equipment, accident prevention regulations, etc. Additional
protective measures might be necessary for applications with increased potential risk.
Do not touch live components or power connections immediately after disconnecting the
MOVIMOT®inverter, the field distributor (if installed) or the bus module (if installed) from
the supply voltage because there may still be some charged capacitors. Wait at least for
1 minute after having switched off the supply voltage.
As soon as supply voltage is present at the MOVIMOT®inverter, the terminal box must
be closed, which means that:
• The MOVIMOT®inverter must be screwed on.
• The terminal box cover of the field distributor (if present) and the bus module (if
present) must be bolted down.
• The connector of the hybrid cable (if installed) must be connected and screwed on.
Note: The maintenance switch of the field distributor (if installed) only disconnects the
connected MOVIMOT®drive or motor from the power supply system. The terminals of
the field distributor remain connected to the line voltage even after the maintenance
switch is activated.
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 supply system and no longer
carries any voltage.
Mechanical blocking or internal safety functions of the unit can cause a motor standstill.
Eliminating the cause of the problem or performing a reset may result in the drive re-
starting automatically. If, for safety reasons, this is not permitted for the driven machine,
disconnect the unit from the supply system before correcting the error.
Caution: Danger of burns: The surface temperature of the MOVIMOT®drive and of
external options, e.g. the heat sink of the braking resistor, can exceed 60 °C during
operation!

5 Electrical Installation
5.1 Installation planning considering EMC aspects
5.1.1 Notes on arranging and routing installation components
Successful installation of decentralized drives depends on selecting the correct cables,
providing correct grounding and a functioning equipotential bonding.
You should always apply relevant standards. You also need to consider the following
points:
•Equipotential bonding
– Low-impedance, HF-capable equipotential bonding must be provided
independent of the functional ground (PE terminal) (see also VDE 0113 or
VDE 0100 part 540) using, for example:
– Flat contact surface connection of metal components
– Flat grounding strips (HF stranded wire)
– Do not use the cable shield of data lines for equipotential bonding.
•Data lines and 24 V supply
– Must be routed separately from cables that emit interference (e.g. control cables
from solenoid valves, motor cables).
•Field distributors
– We recommend using prefabricated SEW hybrid cables especially designed for
connecting field distributors and motors.
•Cable glands
– Select a cable gland with large contact surface shielding (see the notes on
selection and correct installation of cable glands).
1138895627
1138899339

18 Compact Manual – InterBus Interfaces and Field Distributors
5Installation planning considering EMC aspects
Electrical Installation
•Cable shield
– The cable shield must have good EMC characteristics (high shield attenuation),
– It must protect the cable mechanically and as a shield,
– It must be connected with the unit's metal housing (via EMC metal cable glands)
at the flat contact surface cable ends (see the further notes in this chapter on
selection and correct installation of cable glands).
•Additional information is available in the SEW publication "Drive Engineering
– Practical Implementation, EMC in Drive Engineering."
5.1.2 Sample connection between an MF.. / MQ.. fieldbus interface and MOVIMOT®
If the MF../MQ.. fieldbus interface and MOVIMOT®are installed separately, the RS-485
connection must be implemented as follows:
•If the connection also carries the DC 24 V supply
– Use shielded lines
– Apply shielding to the housing of both units via EMC metal cable glands (consult
the other notes in this chapter on appropriate assembly of EMC metal cable
glands as well)
– Strand cores in pairs (see the following illustration)
•If the connection does not carry the DC 24 V supply
If MOVIMOT®is supplied with DC 24 V via a separate connection, the RS-485
connection must be carried out as follows:
– Use shielded lines
– Apply shielding to the housing of both units via EMC metal cable glands (consult
the other notes in this chapter on selection and appropriate assembly of cable
glands as well)
– The GND reference potential must be provided for the RS-485 interface
– Strand the cores (see the following illustration)

5.2 Installation instructions for fieldbus interfaces, field distributors
5.2.1 Connecting supply system leads
• The rated voltage and frequency of the MOVIMOT®inverter must correspond to the
data for the supply system.
• Select the cable cross section according to the input current Iline for rated power (see
Technical Data in the operating instructions).
• Install line fuses at the beginning of the supply system line behind the supply bus
junction. Use D, DO, NH fuses or circuit breakers. Select the fuse size according to
the cable cross section.
• Do not use a conventional earth leakage circuit-breaker as a protective device.
Universal current-sensitive earth-leakage circuit breakers ("type B") are permitted as
a protective device. During normal operation of MOVIMOT®drives, earth-leakage
currents > 3.5 mA can occur.
• In accordance with EN 50178, a second PE connection (at least with the same cross-
section as the supply system lead) is required parallel to the protective earth via sep-
arate points of connection. Leakage currents > 3.5 mA can arise during operation.
• Use contactor switch contacts from utilization category AC-3 according to IEC 158 to
connect MOVIMOT®drives.
• SEW-EURODRIVE recommends using earth-leakage monitors with pulse code
measuring in 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.
5.2.2 Notes on PE connection and/or equipotential bonding
