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

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 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.

RFI Line Filters
4.4 Easy startup
• RFI line filters are designed to slide on to the back of the MOVITRAC® LTP heatsink,
creating a simple integrated assembly. With MOVITRAC® LTE-B the filter is mounted
next to the unit.
• Fixing holes for the combined assembly are the same as for the standalone drive;
longer screws are provided.
• The electrical supply connects to the filter. Connection of the supply earth to the filter
earth is essential, otherwise the filter will not work.
• The filter wire connects to the drive input and drive earth points according to the label
on the wire.
• The filters contain capacitors that are connected between phase and earth; a leak-
age current will flow during normal operation. A good earth connection is therefore
essential and must be connected before applying power to the filter.

Line Chokes
5LineChokes
Most types of drive products create supply harmonic distortion due to the configuration
of the power input circuit. Line chokes reduce supply harmonic distortion and protect the
MOVITRAC®LT against harmful supply disturbances.
Line chokes are also used to protect the power input circuits of the MOVITRAC®LT
against voltage spikes which might originate from lightning strikes or other equipment,
such as welders or DC drives, on the same supply.
MOVITRAC®LTP Sizes 4, 5 & 6 include 3-phase line chokes as part of the product ba-
sic design. This significantly improves the robustness of these products.
An external choke is required if 220 V or 400 V drives from 0.37 kW (0.5 HP) to 5.5 kW
(7.5 HP) are installed under conditions where the quality of the supply cannot be guar-
anteed. Examples of these conditions are:
• Local generator
• Large loads on the same supply
• High dV / dt voltage fluctuations
• Outdoor pumping stations with exposed supply lines, which may be hit by lightning
strikes
• Crane applications
• When supply is via bus bars
An external line choke is always required for MOVITRAC®LTP 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.
