H Ambient Temperature Control
• To enhance operation reliability, the Inverter should be installed in an environment free
from extreme temperature rises.
• 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 surface temperature of the Inverter may reach 30°C higher than the ambient tem-
perature. Therefore, keep all thermally susceptible devices and wires away from the
Inverter.
H Protecting the Inverter from Foreign Matter during Installation
• Place a cover over the Inverter to shield it from metal powder produced by drilling dur-
ing installation.
(Upon completion of installation, always remove the cover from the Inverter. Other-
wise, ventilation will be affected, causing the invert to overheat.)
