Be sure to check the ambient temperature | Hitachi J300U Series

For cooling purposes, be sure that the inverter is installed vertically. In addition, be sure that it is separated from other components and walls. If foreign matter is introduced into the interior of the inverter, this may cause malfunctions, so make sure that no foreign matter can enter it.

NOTE: Install the inverter vertically.

Do not install it on the floor or horizontally. ( ) is for 75 to 260kW

CAUTION

Be sure that the wall surface is a nonflammable material, such as steel plate.

Be sure to check the ambient temperature.

Place of installation	Load characteristics	Ambient temperature	Applicable model

Within the enclosure	Constant torque	-10 to 50°C	All models
(NOTE 1)	Variable torque	-10 to 40°C	(NOTE 2)

NOTE 1: The inverter should be installed in a locked enclosure that meets the requirements in IP4X.

The higher the ambient temperature inside the inverter, the shorter its life will be. If a heat generating unit is used near the inverter, try to keep it as far away as possible. Also, when installing the inverter in a box, be sure to carefully consider ventilation and the dimensions.

NOTE 2: Each of inverters 22 kW to 260 kW must be installed in a locked enclosure.
