Installation Considerations
Inverters are composed of various precision, electronic devices, and therefore the
installation environment can significantly impact the lifespan and reliability of the
product. The table below details the ideal operation and installation conditions for
the inverter.
Ambient Temperature*
- CT (Heavy Duty) load : - 10 ~ 50
℃
(without ice or frost)
- VT (Normal Duty) load : - 10~ 40
℃
(without ice or frost)
(It is recommended that you use less than 80% load when you use
VT load at 50
℃
.)
- IP54 product: -10~40
℃
(without ice or frost)
Ambient Humidity 90% relative humidity (no condensation)
Storage Temperature
- 4–149
F (-20–65
℃
)
Environmental Factors
An environment free from corrosive or flammable gases, oil residue
or dust
Altitude/Vibration
Lower than 3,280 ft (1,000 m) above sea level/less than 0.6 G (5.9
m/sec
2
)
Air Pressure 70 –106 kPa
* The ambient temperature is the temperature measured at a point 2” (5 cm) from the
surface of the inverter.
