Chapter 4 – Installation
The inverter must be mounted vertically on a non-flammable wall in order to prevent from overheating and
fire. The minimum clearances to the surrounding walls shown in the figure below must be complied with to
ensure a good ventilation. Foreign matter (especially conductive objects) must nut be dropped into the
inverter since they not only cause malfunction and damage but may also lead to electrical and fire hazards.
Cover all ventilation holes on the inverter during installation so that no foreign objects can enter the inverter.
Be sure to remove those covers from the inverter before you put the inverter to work.

The inverter must be installed vertically
The mounting base must be a non-
(do not install it on the floor or horizontally)
flammable material (e.g. metal)
The minimum clearances to the surrounding walls shown in the figure are only meant for reference. A more
compact installation (back to back or side by side) may well be possible and should be discussed with
Hitachi. Please always leave enough room for the teminal cover to be opened without problems in order to
connect wires to the control terminals.
The ambient temperature should be in the range of -10°C to 40°C. Higher ambient temperature causes shorter
inverter life. So if there is hot equipment in the vicinity of the inverter, keep it away from the inverter as far
as possible.
The end application must be in accordance with the BS EN 60204-1 standard.
