Installation
Chapter 2-1
Installation Direction and Dimensions
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.
Direction
Install the Inverter on a vertical surface so that the characters on the
nameplate are oriented upward.
Dimensions
When installing the Inverter, always provide the following clearances to allow
normal heat dissipation from the Inverter.
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.
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.
