CAUTION
The surfaces of the unit and any connected components, e.g. braking resistors, can
reach high temperatures during operation.
Danger of burns.
• Let the unit and external options cool down before you start working on them.
Do not deactivate monitoring and protection devices even for a test run.
When in doubt, switch off the unit whenever changes occur in relation to normal mode
(e.g. increased temperatures, noise, oscillation). Determine the cause of the fault and
consult SEW-EURODRIVE, if necessary.
Where required, systems in which such units are installed must be equipped with additional monitoring and protection devices in accordance with the respective applicable
safety regulations, e.g. the law governing technical equipment, accident prevention
regulations, etc.
Additional protective measures may be necessary for applications with increased potential risk. You have to check the effectiveness of protection devices each time you change
the configuration.
Connections which are not being used must be covered with the supplied protection
caps during operation.
Do not touch live components or power connections immediately after disconnecting the
unit from the voltage supply because some capacitors may still be charged. Adhere to
a minimum switch-off time of 10 minutes. Observe the corresponding labels on the unit.
When the unit is switched on, dangerous voltages are present at all power connections
as well as at any connected cables and motor terminals. This also applies even when
the unit is inhibited and the motor is at standstill.
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 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.

4.2.3 IP20 housing: Installation and control cabinet dimensions
For applications that require a higher IP protection level than IP20, the inverter must be
installed in a control cabinet. Observe the following requirements:
• The control cabinet must be made of a heat conductive material unless it has forced
cooling.
• When using a control cabinet with ventilation openings, the openings must be provided above and underneath the inverter to allow for unobstructed circulation of air.
The air must be supplied underneath the inverter and dissipated above it.
• If the inverter is operated in environments with particles of dirt (such as dust), ventilation openings either have to be equipped with a suitable particle filter or forced cooling has to be used. The filter has to be serviced and cleaned.
• In environments with a high level of humidity, salt or chemicals, a suitable enclosed
control cabinet (without ventilation openings) must be used.

4.3.2 Installation
Installation
Electrical installation
Connect the inverter as shown in the following wiring diagrams. Ensure proper wiring in
the motor terminal box. Two basic connections are distinguished: Star connection and
delta connection. It is essential that you make sure that the motor is connected with the
voltage source in such a way that it is supplied with the proper operating voltage. You
find more information in the figure in section "Connection in the motor terminal box"
(page 24).
It is recommended that you use a 4-core PVC-insulated and shielded cable as the power
cable. Route this cable according to the applicable national regulations of the industry
sector as well as the rules and standards. Conductor end sleeves are required for connecting the power cables to the inverter.

Permitted voltage
supply systems
Line contactors and line fuses
Line contactors Use only line contactors in utilization category AC-3 (EN 60947-4-1).
Line fuses Fuse types:
• Voltage supply systems with grounded star point
®
MOVITRAC
directly grounded star point.
• Voltage supply systems with non-grounded star point
Operation on voltage supply systems with non-grounded star point (for example IT
systems) is also permitted. For this purpose, SEW-EURODRIVE recommends to use
an earth-leakage monitor according to the pulse-code measurement principle. Using
these devices avoids the earth-leakage monitor from tripping by mistake due to the
missing capacitance to ground of the inverter.
• Outer conductor grounded voltage supply systems
On voltage supply systems, the inverters may only be operated with a maximum
phase-to-ground AC voltage of 300 V.
It is important that a minimum time interval of 120 seconds is adhered to between two
voltage supply system activations.
• Line protection types in operation classes gL./ gG:
LTE-B inverters are designed for operation on TN and TT systems with
– Nominal fusing voltage ≥ nominal line voltage
– The nominal fusing current must be designed for at least 100% of the nominal in-
verter current depending on the inverter utilization.
• Power circuit breaker with characteristics B, C:
– Nominal circuit breaker voltage ≥ nominal line voltage
– The nominal currents of the power circuit breakers must be 10% higher than the
nominal inverter current.
