H Installation Direction and Dimensions
• Install the Inverter under the following conditions.
Ambient operating temperature:
Panel-mounting models (conforming to IP20): –10 to 50°C (0.1- to 3.7-kW Inverters)
Closed wall-mounting models (conforming to NEMA1 and IP20):
–10 to 40°C (5.5- to 7.5-kW Inverters)
Humidity: 95% max. (with no condensation)
Note 1. By removing the top and bottom covers from a 5.5- to 7.5-kW Inverter, it can be used as a
panel-mounting model (conforming to IP00) within an ambient temperature range of –10 to
50°C.
Note 2. All C-type Inverters (closed wall-mounting models: NEMA1-type for North America) are
closed wall-mounting models, and can be used within an ambient temperature range of –10 to
40°C. If the top and bottom covers are removed, the C-type Inverters can be used as panel-
mounting models (conforming to IP00) within an ambient temperature range of –10 to 50°C.
• Install the Inverter in a clean location free from oil mist and dust. Alternatively, install it in a totally
enclosed panel that is completely protected from floating dust.
• When installing or operating the Inverter, always take special care so that metal powder, oil, water, or
other foreign matter does not get into the Inverter.
• Do not install the Inverter on inflammable material such as wood.
• If a 5.5- to 7.5-kW Inverter or a C-type Inverter is to be installed inside of a control panel, it must have
the top and bottom covers removed and be used as a panel-mounting model (conforming to IP00).
H Direction
• Install the Inverter on a vertical surface so that the characters on the nameplate are oriented upward.
H Dimensions
• When installing the Inverter, always provide the following clearances to allow normal heat dissipation
from the Inverter.
W = 30 mm min. (0.1 to 4.0 kW)
50 mm min. (5.5 to 7.5 kW)
Inverter
100 mm min. Air
SideInverter Inverter
100 mm min. Air
