Preparation for installing the unit
CAUTION
Facilitate the flow of air entering through the cooling grids.
Ingeteam does not guarantee the proper operation of the equipment if the operation conditions for which it has
been designed are not fulfilled.
Operation of the inverter at temperatures greater than 122 ºF (50 ºC) should only occur occasionally and
not permanently. Ingeteam is not responsible for the consequences to the unit resulting from operating it at
temperatures higher than 122 ºF (50 ºC).
Installation in cabin
Adequate ventilation must be provided and the following requirements met to guarantee proper operation within
the whole range of temperatures for which the equipment was designed:
• If installing the equipment in a cabin or closed precinct, you must make sure that the airflow is at least
60.82 ft /s (6,200 m
3
• These inverters come with filters in the air inlet. Ingeteam recommends a filter in the air vent inlet of the
class G4 cabin (in accordance to the EN779 standard). We recommend a separation of 1.18 in (3 cm)
between the air inlet vent and the filter.
• For correct cooling appropriate to the filters installed in the unit, air quality must be guaranteed to
environmental class 3S2, in accordance with standard EN 60721-3-3.
• The entry of air to the cabin or enclosed location must be dimensioned such that the speed of the air
intake is less than 9.84 ft/s (3 m/s).
• Total permissible pressure loss in the cabin ventilation system (inlet grille and filter, air outlet duct and
outlet grille) for the total required flow rate is a maximum of 2.09 lb/ft
• Ingeteam recommends installing an air outlet duct (plenum) to facilitate the extraction of the hot air
generated by unit operation to the outside of the cabin or enclosed location. The installation of this
plenum must guarantee that the air expelled by the inverter does not return to the interior of the cabin or
closed precinct. The construction of a plenum with a slight slope towards the outside is recommended to
prevent accumulation and entry of water to the unit.
