• Install the Inverter under the following conditions.
Ambient temperature for operation (panel-mounting): –10°C to 50°C
Humidity: 95% or less (no condensation)
• 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.
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.
Inverter
100 mm min. Air
SideInverter Inverter
100 mm min. Air
H Ambient Temperature Control
• To enhance operation reliability, the Inverter should be installed in an environment free from extreme
temperature changes.
• If the Inverter is installed in an enclosed environment such as a box, use a cooling fan or air conditioner
to maintain the internal air temperature below 50°C.
The life of the built-in electrolytic capacitors of the Inverter is prolonged by maintaining the internal air
temperature as low as possible.
• The surface temperature of the Inverter may rise approximately 30°C higher than the ambient temperature. Be sure to keep away equipment and wires from the Inverter as far as possible if the equipment
and wires are easily influenced by heat.
