energy and improper handling. Electric components must not be mechanically damaged
or destroyed.
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.
(frequency inverter may only be operated in climate class 3K3 to EN 60721-3-3)
• Use in non-stationary applications which are subject to mechanical vibration and
impact loads in excess of the requirements in EN 61800-5-1.
2.6 Electrical connection

Safety Notes
2.8 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.
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.
Integral solid state short circuit protection does not provide branch circuit protection.
Branch circuit protection must be provided in accordance with the National Electrical
Code and any additional local codes.
Do not touch live components or power connections until 10 minutes 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 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.
2.9 Operation and servicing
• Dangerous voltages are present in the output terminals and the cables and motor
terminals connected to them when the unit is switched on. Dangerous voltages may
also be present when the unit is inhibited and the motor at a standstill.
• The unit is not necessarily deenergized when the LEDs and the 7-segment display
are off.
• 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 auto-
matic restart of the drive. If, for safety reasons, this is not permissible for the driven
machine, disconnect the unit from the supply system before correcting the fault.
WARNING
Danger of electrical shock. High voltages are present in the terminals and in within the
drive for up to 10 minutes after the electrical supply has been disconnected.
Severe or fatal injuries.
• Disconnect and isolate the MOVITRAC® LTP from the electrical supply at least 10
minutes before commencing any work on it.

4.2 IP20 / NEMA 1 housing: mounting and dimensions
For applications that require a higher IP rating than the IP20 offered by the standard
drive, the drive must be mounted in housing. The following guidelines should be
observed for these applications:
• Housing should be made from a thermally conductive material, unless forced venti-
lation is used.
• When vented housing is used, there should be venting above and below the drive to
ensure good air circulation. Air should be drawn in below the drive and expelled
above the drive.
• If the external environment contains contamination particles (e.g. dust), a suitable
particle filter should be fitted to the vents and forced ventilation implemented. The
filter must be serviced and cleaned appropriately.
• High moisture, salt or chemical content environments should use a suitably sealed
(non-vented) housing.

5 Electrical Installation
It is essential to comply with the safety instructions in chapter 2 during installa-
tion.
•MOVITRAC
® LTP units should only be installed by qualified electricians and in
accordance with local and national regulations and codes of practice.
• The MOVITRAC® LTP has an Ingress Protection rating of IP20. For higher IP ratings,
use a suitable enclosure or the IP55 version.
• Where the electrical supply to the drive is through a plug and socket connector, do
not disconnect until 10 minutes have elapsed after turning off the supply.
• Ensure correct earthing connections. See diagram in chapter "Drive and motor
connection" on page 23.
• The earth cable must be sufficient to carry the maximum supply fault current, which
is normally limited by the fuses or motor circuit breaker.
5.1 Prior to installation
• Ensure that the supply voltage, frequency and number of phases (single or 3-phase)
correspond to the rating of the MOVITRAC® LTP as delivered.
• An isolator or similar should be installed between the power supply and the drive.
• Never connect the mains power supply to the MOVITRAC® LTP output terminals
U, V or W.
• When installing 575 V inverters ensure the motor is always in STAR connection.
• The cables are only protected when slow blow HRC fuses or a motor circuit breaker
(MCB) are used.
• Do not install any type of automatic switchgear between the drive and the motor.
Wherever control cabling is close to power cabling, maintain a minimum separation
of 100 mm and arrange crossings at 90°.
• Ensure that screening or armoring of power cables is effected in accordance with the
connections diagram in chapter "Drive and motor connection" on page 23.
• Ensure that all terminals are tightened to the appropriate torque.
WARNING
Danger of electrical shock. High voltages are present in the terminals and in within the
drive for up to 10 minutes after the electrical supply has been disconnected.
Severe or fatal injuries.
• Disconnect and isolate the MOVITRAC® LTP from the electrical supply at least
10 minutes before commencing any work on it.
