Positioning in the electrical box
Environmental condition
The electrical box must have suitably filtered air vents.
Leave the necessary space both above and below the converters.
Periodically check drive case and fans for excess dust or dirt, that could interfere with the
correct dissipation of the drive.
This power drives are intended only for use in close locations, guarded from operator
contact, in an ambient that compliance with these characteristics: operating temperature
of maximum 45°C "see the t able below", Humidity limits between 5% to 95% non condensing
(Pollution degree 2 or better).
The drive is natural convection air flow cooled. To ensure the drive cooling and make the
installation easier for the operator it must be installed vertically leaving a free space of at
least 20 mm (0,78 inch) on each side of the device. Avoid mounting heat producing
equipment in the nearest of the drive or any other device that can obstruct natural or forced
convention air flow. For environment temperature above 45°C, forced air cooling is required.
Conductive mounting panel (zinc coated)
Supplementary ventilation may be requested in accordance to size. See the table below.
