5.5  Switch on/off (option SW) 

If switch on/off (SW) is selected, the default positioning is for horizontal airflow installation. 

The cover design is such that it can be used both for horizontal and vertical airflow installation. 

To adjust the switch positioning to the actual positioning on site: unscrew the cover fixing screws, 

turn it as shown and replace fixing screws.

5.6  Switchboard fan speed control (option FT)

If fan speed control (FT) is selected, the default positioning of the switchboard is for vertical airflow 

installation. For application with horizontal airflow, unscrew switchboard and remount in position as 

indicated below. The cover plate should always be positioned horizontally to protect the electrical 

components.
