4.1 General information
• Before installation, check the inverter carefully to make sure it is not damaged.
• Store the inverter in a box until it is used. The inverter must be stored at temperatures
between –40 °C and +60 °C and in such a way that it is clean and dry.
• Install the inverter on a level, horizontal, flameproof and vibration-proof surface in a
suitable control cabinet. If a special degree of protection (IP) is required, the control
cabinet must comply with EN 60529.
• Do not store or use flammable substances in the vicinity of the inverter.
• Make sure no conductive or flammable objects enter the inverter.
• The maximum ambient temperature during operation is 50 °C for IP20 inverters, and
40 °C for IP55 and IP66 inverters. The minimum ambient temperature during opera-
tion is -10 °C.
Note the special degrees of protection in section "Information on ambient conditions"
(page 52).
• The relative humidity must be below 95% (non-condensing).
• MOVITRAC

LTE-B units can be installed directly next to one another. There is still
sufficient clearance for ventilation between the units.
If you install the inverter above another inverter or device that generates heat, adhere
to a minimum clearance of 150 mm. The control cabinet must either be cooled
through forced ventilation, or has to be big enough to dissipate the heat itself, see
section "IP20 housing: Installation and control cabinet dimensions" (page 19).
• A DIN assembly kit for mounting rails is supported only for inverter sizes 1 and 2
(IP20).

Housing variants

LTE-B is available with three housing variants:
• IP66 / NEMA 4X
• IP55 / NEMA 12K
• IP20 housing for installation in control cabinets
IP55 / NEMA-12K and IP66 / NEMA-4X housings are protected against humidity and
dust. This is why these inverters can be operated indoors in a dusty or damp environ-
ment. The electronics of the inverters does not differ. The only difference is in the hous-
ing dimensions and the weight.
In degrees of protection IP55 and IP66, the inverters are also available with switch op-
tions, such as main switch, direction of rotation switch, and potentiometer.
