Toshiba TOSVERT VF-AS1 Instruction Manual page 32

Installation place
Install the inverter in a well-ventilated indoor place and mount it on a flat metal plate in portrait orientation.
If you are installing more than one inverter, the separation between inverters should be at least 5cm, and they should be
arranged in horizontal rows.
If the inverters are horizontally arranged with no space between them (side-by-side installation), remove of the
protective cover on top of the inverter. It is necessary to decrease the current if the inverter is operated at over 50°C.
・Standard installation
5cm or more
The space shown in the diagram is the minimum allowable clearance. Make the space on top and bottom as large as
possible to allow for air passage.
For models designed for 110kW motors or larger, leave a space of 50cm or more above and below the inverter.
Note: Do not install in any location where there is high humidity or high temperatures and where there are large
amounts of dust and metallic fragments. If you are going to install the equipment in any area that presents a
potential problem, please consult with your supplier before doing so.
Current reduction curve
Depending on the way in which the inverter is installed, the ambient temperature and the carrier frequency setting,
you may need to reduce the inverter's continuous output current.
