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
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 temper-
ature. 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.
H Protecting Inverter from Foreign Matter during Installation
• Place a cover over the Inverter during installation to shield it from metal power produced by drilling.
Upon completion of installation, always remove the cover from the Inverter. Otherwise, ventilation will
be affected, causing the Inverter to overheat.
