Fixings
check the correct fixing of the cabinet components to their corresponding anchorage points.
ensure adequate ventilation of the unit
checking the status of exhaust fans, cleaning and replacing them if necessary.
The useful life of the fans is 8 years, so they must be replaced after this time even if they seem to
be functioning normally.
The lower fans on the power modules may be replaced by accessing them via the doors of the modules. The upper
fans may be accessed via the roof of the unit.
clean vents grids
check the state of the filters in the front and side ventilation grids.
To do this you must first remove the grille of the air intake, behind which is the filter.
• unscrew the four nuts from the grid, accessible from the inside of the door.
• Remove the grid.
• Remove the filter from inside the grid.
Accumulated dust and dirt in the filter may adversely affect the cooling ability of the fan and result in anomalous
heating of the equipment. To solve this problem, clean and replace the filter and grid:
• With a moderately dirty, dry filter, lightly tap until the dirt has been removed.
• If the dirt does not disappear, wash in water at 40 °c.
• If the filter is soiled with grease or oil, replace it with a new one.
If the problem persists, contact Ingeteam.
When on, the inverter generates a buzzing sound.
check the environment to avoid amplifying or transmitting the buzz.
The unit should be located in a place readily accessible for installation and maintenance work, enabling keyboard
handling, display reading and access to the unit's various internal components.
check the status of the relays
The intake board contains several relays which must be checked annually. check visually, always with no power
connected to the equipment, that there is no darkening of the surrounding caused by heading and that the stand-by
position is correct.
They must be replaced if any anomaly is observed.
