The following basic safety notes must be read carefully to prevent injury to persons and
damage to property. The operator must ensure 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 instruc-
tions 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 Preliminary information
The following safety notes predominantly refer to the use of frequency inverters and their
accessories. Additionally, when using drives with motors or gearmotors, observe the
corresponding safety notes in the respective operating instructions.
Please also observe the supplementary safety notes in the individual sections of this
document.
2.2 General

2.4 Designated use
Frequency inverters and their accessories are components for controlling asynchronous
AC motors. Frequency inverters are components intended for installation in electrical
systems or machines. Never connect capacitive loads. Operation with capacitive loads
results in over voltages and may destroy the unit.
The following standards apply, if the frequency inverters are marketed in the EU / EFTA:
• In case of installation in machines, startup of the drive inverters (meaning the start of
proper use) is prohibited until it is determined that the machine meets the require-
ments stipulated in the EC Directive 98/37/EC (machine directive); observe
EN 60204.
• Startup (i.e. the start of designated use) is only permitted under observance of the
EMC (2004/108/EC) directive.
• The frequency inverters comply with the requirements of the Low Voltage Directive
2006/95/EC. 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 frequency inverters.
Observe the technical data and the connection requirements specified on the nameplate
and the operating instructions.
2.4.1 Safety functions
Frequency inverters from SEW-EURODRIVE must not perform any safety functions
unless the inverters are subordinate to other safety systems.
Use higher-level safety systems to ensure protection of equipment and personnel.

2 Transport
Safety Notes
2.5 Transport
Immediately upon receipt, inspect the shipment for any damagethat may have occurred
during transportation.
Never install or start up damaged products. In the event of damage please submit a
complaint to the transport company immediately.
2.6 Installation / assembly
The units must be installed and cooled according to the regulations and specifications
in this documentation.
Protect the frequency inverters from excessive strain. Do not twist any components and
do not modify the insulation spaces. Do not touch any electronic components or
contacts.
Frequency inverters contain components that can easily be damaged by electrostatic
energy and improper handling. Electric components must not bemechanically damaged
or destroyed.
The unit meets all requirements for reliable isolation of power and electronics
connections in accordance with UL508. All connected circuits must also satisfy the
requirements for reliable isolation so as to guarantee reliable isolation.
Take suitable measures to ensure that the connected motor does not start up
automatically when the inverter is switched on. To do this, connect binary inputs DI01
through DI03 to GND / 0V.
The following applications are prohibited unless the unit is explicitly designed for such
use:
• Use in potentially explosive atmospheres.
• Use in environments with harmful substances:
– Oils
–Acids
– Gases
– Vapors
–Dust
– Radiated interference
– Other harmful environments
• Use subject to mechanical vibration and shock loads in excess of the requirements
in EN 50178.
• Use in non-stationary applications which are subject to mechanical vibration and
impact loads in excess of the requirements in EN 61800-5-1.
• If the inverter or its accessories perform safety functions which have to guarantee the
protection of machinery and people.

Electrical connection
Safety Notes
2.7 Electrical connection
Observe the applicable national accident prevention guidelines when working on live
frequency inverters (e.g. BGV A3 for Germany).
During installation, observe the specifications regarding cable cross sections, fusing and
protective conductor connection.
Protective measures and protection devices must comply with the regulations in force
(e.g. EN 60204 or EN 61800-5-1).
– Grounding the unit is a necessary protective measure.
– Overcurrent protection devices are a necessary protective measure.
2.8 Safe disconnection
The MOVITRAC®LT units and their accessories 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.
2.9 Startup / operation
Systems with integrated frequency inverters must be equipped with additional monitor-
ing and protection devices, as applicable, according to the relevant safety guidelines
and regulations, such as legislation governing technical equipment, accident prevention
regulations, etc.
Do not touch live components or power connections until 10minutes after disconnecting
the frequency inverters from the supply voltage because there may still be some
charged capacitors. Observe the corresponding labels on the frequency 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 mains and no longer carries
any voltage.
Mechanical blocking or safety functions inside the unit may result in the motor coming
to a standstill. Eliminating the cause of the problem or performing a reset may result in
the drive restarting automatically. If, for safety reasons, this is not permitted for the
driven machine, disconnect the unit from the supply system before correcting the error.

2 Operation and servicing
Safety Notes
2.10 Operation and servicing
WARNING
Dangerous voltages are present in the output terminals and the cables and motor
terminals connected to them when the unit is switched on.
The unit is not necessarily deenergized when the LEDs and the 7-segment display
are off. Dangerous voltages may also be present when the unit is inhibited and the
motor at a standstill.
High voltages are also present in the terminals and within the drive for up to 10 min-
utes after the electrical supply has been disconnected.
Severe or fatal injuries from electric shock.
• Disconnect and isolate the MOVITRAC®LT from the electrical supply at least
10 minutes before commencing any work on it.
WARNING
Safety functions inside the unit or a mechanical blockage may cause the motor to
stop. The removal of the source of the malfunction or a reset can result in an
automatic restart of the drive.
Severe or fatal injuries.
•Disconnect the unit from the supply system before correcting the fault.

4.5 Operation
4.5.1 Switching between a voltage and a current speed reference
• Connect the voltage signal to terminal 6 and the current signal to terminal 7 of the
option module.
– Each of these signals is referenced to terminal 9 (0 V).
– The digital signal used to switch between the voltage and current inputs should
be connected to terminal 4 (digital input 3).
• Set the parameters as follows:
– P-19 = 0
– P-16=4–20mA (or0–20mA/20–4mA,dependingonrequiredformat)
4.5.2 Hand – Off – Auto-operation
• Connect the required analog reference signals to terminals 6 and 7 as described
above. This mode of operation requires a 2-pole change-over, centre-off switch.
– The first pole of the switch is used to enable the drive, where both "Hand" and
"Auto" positions should be connected to digital input 1.
– The second pole of the switch is connected to digital input 3, as described above.
• Connect the common connection point of each of the switches to terminal 1 (0 V).
• In a typical configuration, "Hand" will enable the drive using the voltage (local) refer-
ence, "Auto" will enable the drive using the current (remote) reference.
TIP
When digital input 3 is open, the voltage format signal (connected to terminal 6) will be
selected.
