Unless the information in the operating instructions is adhered to, it will be impossible to
ensure:
• Trouble-free operation
• Fulfillment of any rights to claim under guarantee
Consequently, read the operating instructions before you start working with the
unit!
The operating instructions contain important information about servicing. Therefore,
keep the operating instructions close to the unit.

2.2 Operation and servicing
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
minutes before commencing any work on it.
• 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
automatic 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.

Products used with a 3-phase supply are designed for a maximum supply imbalance of
3 % between phases. For input supplies which have a supply imbalance greater than
3 % (typically the Indian subcontinent and parts of Asia Pacific including China) we
recommend that input chokes are used.

MOVITRAC® LTP is available in 2 housing versions:
• Standard IP20 / NEMA 1 housing for use in switch cabinets
• IP55 / NEMA 12 K version for size 1 and size 2 drives
The IP55 / NEMA 12 K housing is protected against moisture and dust. Therefore, the
drives can be operated indoors under harsh conditions. Electronically, the drives are
identical and the only differences are the dimensions of the housing and the weight.

IP20 / NEMA 1 housing: mounting and dimensions
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 ventilation 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.

• The MOVITRAC
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 20.
• The earth cable must be sufficient to carry the maximum supply fault current which
normally will be limited by the fuses or motor circuit breaker.

•MOVITRAC
Use monitoring systems or mechanical protection devices to ensure safety.
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
• An isolator or similar should be installed between the power supply and the drive.
• Never connect the mains power supply to the MOVITRAC
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 20.
• Ensure that all terminals are tightened to the appropriate torque.

NOTE
• Connect the brake rectifier using a separate supply system lead.
• Supply via the motor voltage is not permitted!
The 230 V and 400 V drives do not require a line choke on the supply unless the specified supply voltages cannot be guaranteed.
Drives from 0.37 kW (0.5 HP) to 5.5 kW (7.5 HP) must be fitted with external line chokes
if the quality of the supply cannot be guaranteed.
An external line choke is always required for 575 V drives from 0.75 kW (1 HP) to 5.5 kW
(7.5 HP).
All drives with 7.5 kW (10 HP) or greater have a built-in choke and therefore do not need
external chokes fitted to ensure transient protection.
An external choke is required if 230 V or 400 V drives up to 5.5 kW (7.5 HP) are installed
under the following conditions:
• Local generator
• Large loads on the same supply
• High dV / dt voltage fluctuations e.g. when welders are being used
• Outdoor pumping stations with exposed supply lines, which may be hit by lightening
strikes.
Always switch off the brake on the DC and AC sides with:
• All hoist applications
• Drives that require a rapid brake response time

It is essential to adhere to the connection sequence of the brake connector. Incorrect
connection will lead to irreparable damage to the brake. The connection to the brake
rectifier requires a separate supply system cable. Supply from the motor voltage is not
permitted.
If the brake rectifier is installed in the switch cabinet the connecting cable between the
brake rectifier and the brake must be routed separately to other power cables. Routing
together with other cables is only permitted if the other cables are shielded. Set P2-13
to 3 to use the relay output to control the brake rectifier (BGx).
5.2.3 Motor thermal protection (TF / TH)
Motors with an internal PTC over-temperature sensor (TF, TH or similar) can be connected directly to the MOVITRAC
The sensor is connected to terminal 1 (+24 V) and Digital Input 3. Parameter P2-01 must
be set to external trip input to receive over-temperature trips. The trip level should be set
to 2.5 k
Ω.

LTP. A trip will then be displayed on the drive.

5.2.4 Signal terminal overview
IP20 and IP55 IP55 with switch option
The User Control terminals are available via an 11-way pluggable connector. All terminals are galvanically isolated, allowing direct connection to other equipment.
STOP!
Danger of damage to the MOVITRAC® LTP unit.
Do not connect mains supply voltages to any terminals other than the user relay output.
Doing so will result in permanent damage to the unit.
The user relay output can handle up to AC 250 V. All other inputs only withstand
DC 30 V without damage.
The functionality of the inputs and outputs is user configurable. All operating modes are
set up via the parameter set.
Up to 100 mA can be sourced from the User +24 V output and up to 20 mA from the
analog output.

5.3 Optical interface
The optical interface, which is located next to the RJ11 connector, is mainly used for
commissioning and monitoring the drive with a pocket PC. When LTP shell CE is
installed, the pocket PC can be used to commission the drive and monitor the current
status of the drive.
5.4 UL-compliant installation
Note the following for UL-compliant installation:
• The drives can be operated within an ambient temperature of 0 ... 50 °C.
• Only use copper connection cables which can withstand ambient temperatures of up
to 75 °C.
• Permitted tightening torques for MOVITRAC

LTP drive inverters are suitable for operation in voltage power systems
with an earthed star point (TN and TT systems), which can supply a maximum supply
current and a maximum supply voltage in accordance with the following table. The fuses
listed in the following tables are the maximum permitted fuses for each inverter. Only
use melting fuses.
Only use tested units with a limited output voltage (V
= DC 30 V) and limited output
max
current (I = < 8 A) as an external DC 24 V source.
UL certification does not apply to operation in voltage supply systems with a non-earthed
star point (IT systems).
