4.3.1 IP20 housing: Installation and installation space
Inverters with degree of protection IP20 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.
• The inverters with degree of protection IP20 can be installed right next to each
other without clearance.

4.4.1 Before installation
22872051/EN – 09/2016
• The inverters may only be installed by electrical specialists in compliance with the
applicable directives and regulations.
• The grounding cable must be designed for the maximum fault current of the
voltage source that is usually limited by fuses or motor protection switches.
• The inverter has the degree of protection IP20. For a higher IP degree of protection, a suitable enclosure or the IP55/NEMA 12K or the IP66/NEMA 4X variant has
to be used.
• Make sure the devices are properly grounded. Adhere to the wiring diagram in
chapter "Connecting the inverter and motor"(→249).
• Make sure that supply voltage, frequency, and number of phases (single- or threephase) correspond with the nominal values of the inverter on delivery.
• A disconnecting switch or similar disconnecting element must be installed between
voltage supply and inverter.
• Never connect the power supply to the output terminals U, V or W of the inverter.
• Do not install contactors between inverter and motor. Adhere to a minimum clearance of 100 mm at points where control cables and electric power lines are installed close to each other, and an angle of 90°for crossing cables.
• The cables are only protected by slow-blow high-power fuses or motor circuit
breaker. You find more information in section "Permitted voltage supply
systems"(→227).
• 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.
• Make sure that shieldings and sheaths of power cables are designed according to
the wiring diagram in section "Connecting inverter and motor"(→249).
• The grounding terminal of each inverter must be connected individually and dir-
ectly to the ground busbar (mass) of the installation site (via filter, if available).

• Do not loop the ground connections of the inverter from one inverter to the other.
Neither route the ground connections to the inverters from other inverters.
• The impedance of the ground circuit must comply with the local safety regulations
of the industry sector.
• Make sure that all terminals are tightened with the respective tightening torques,
see chapter "Technical data"(→2173).
• To comply with UL regulations, all earth connections must be designed with UL listed crimping cable lugs.
Unlike direct operation in the supply system, inverters on the motor generate suitable
fast-switching output voltages (PWM). In the case of motors wound for operation with
adjustable-speed drives, no further preventive actions are necessary. If, however, the
insulation quality is unknown, contact the manufacturer of the motor because preventive actions may be necessary.
INFORMATION
Make sure that the earth connections are properly connected. The inverter can generate leakage currents > 3.5 mA. The grounding cable must be sufficiently dimensioned to carry the maximum fault current of the voltage source that is usually limited
by fuses or miniature circuit breakers. Sufficiently rated fuses or miniature circuit
breakers must be integrated into the inverter's mains supply in accordance with local
laws and/or regulations.
4.4.2 Line contactors
Use only line contactors in utilization category AC-3 (EN60947-4-1).
Make sure to wait at least 30seconds between 2 switching cycles.

4.4.5 Operation on a TN system with an RCD switch (IP20)
IP20 inverters with integrated EMC filter (such as MOVITRAC®LT xxxx xAx-x-00 or
MOVITRAC®LT xxxx xBx-x-00) have a higher leakage current than devices without
EMC filter. The EMC filter may cause errors when operated with a RCCB. Deactivate
the EMC filter to reduce the leakage current. To do so, screw out the EMC and VAR
screw on the side of the device. See figure in chapter "Operation on an IT
system"(→226).
4.4.6 Permitted voltage supply systems
• Voltage supply systems with grounded star point
Inverters with all degrees of protection are intended for operation on TN and TT
systems with 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 only permitted for inverters with degree of protection IP20. See chapter
"Operation on an IT system"(→226).
