1.5 Ambient conditions

Positioning in the electrical box

Follow the instructions in the positioning of the servodrive in the electrical box.
- The drive is natural convection air flow cooled.
- To ensure the drive cooling and make the installation easier for the operator it must be in-
stalled vertically leaving a free space of at least 20 mm (0,78 inch) on each side of the device. 
The converter must be mounted vertically on the electrical box. In case you want to mount it 
horizontally, remove the cover.
- The electrical box must have suitably filtered air vents.
- Leave the necessary space both above and below the converters.
- Keep the drive from excessive mechanical vibration

Notes during the assembly

Caution: during the wiring of the servodrive in the electrical box, make sure that do not enter 
leading wires of copper or iron chips through the slits. Before performing the work cover the 
holes with a piece of paper tape. Naturally finished work this tape is removed.

1.6 Ventilation

This servodrive are intended only for use in close locations. Ambient characteristics: operating 
temperature from 0 to +40°C. Humidity limit s between 5% to 95% non condensing (Pollution 
degree 2 or better).
Supplementary ventilation may be requested in accordance to size. See the table below.
