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 temperature. There-
fore, 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 during installation.
(Upon completion of installation, always remove the cover from the Inverter. Otherwise, ventilation
will be affected, causing the invert to overheat.)
