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