Controlling The Ambient Temperature; Protecting The Inverter From Foreign Matter - YASKAWA FSDrive-MV1S Instructions Manual

Controlling the Ambient Temperature

To enhance reliability of operation, the Inverter should be installed in an environment free from extreme tem-
perature variations. The ambient temperature and the temperature of incoming air to the panels must be 40°C
or below.
If the Inverter is installed in a room of limited space, such as a small electric room, where the room tempera-
ture may easily increase, use a cooling fan or air conditioner to maintain the room temperature at 40°C or
below.

Protecting the Inverter from Foreign Matter

Take measures to prevent foreign matter such as metal chips or powder from entering the Inverter during
installation.
Make sure that tools and unused parts are not left in or around the panels after installing the Inverter. Carefully
check the power flow sections, their surroundings, the air filter section, and the ventilation louver on the top of
panels, and confirm that there are no foreign objects or obstacles.
