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. (200V-55kW or lager and 400V-90kW or larger models dose not need to
remove the protective cover) If the inverters are installed where the ambient temperature is above 45 or 50°C, which
depends on their capacities, the current needs to be lowered.

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 200V-90kW and 400V-132kW motors or larger, leave a
space of 30cm or more above and below the inverter.
Note1: For models designed for 200V-75kW and 400V-110kW motors or larger, leave a space of 30cm or more above
and below the inverter.
Note2: 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 contact your Toshiba 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.
Reduction rates vary depending on the capacity of the inverter. The capacities shown in these diagrams are
capacities with the highest reduction rates. Refer to section 12, you can find 100 % value of output current there.
The VFPS1 has the function of adjusting the inverter’s overload resistance automatically according to the ambient
temperature, as shown in the figure below. This function enhances the inverter’s overload resistance when the
ambient temperature is low. To use this function, set the parameter
to .
If
is set to (default setting), protection will be provided by reducing the output current (approximate linear
reduction) in 12, “Specifications,” by adjusting the PWM carrier frequency or at the occurrence of the event shown
in the diagram below, which occurs first.
