2.1.1 Installation
(1) Transportation
This inverter has plastic parts. So handle with care.
Do not over tighten the wall mounting fixings as the mountings may crack, causing is a risk of
falling.
Do not install or operate the inverter if there appears to be damaged or parts missing.
(2) Surface for the mounting of inverter
The temperature of the inverter heatsink can rise very high.
The surface, to which the inverter will be mounted, must be made of a non-flammable
material(i.e steel) due to the possible risk of fire. Attention should also be made to the air gap
surrounding the inverter. Especially, when there is a heat source such as a breaking resistor
or reactor.

(3) Operating
Environment-Ambient
Temperature
The ambient temperature surrounding the inverter should not exceed the allowable
temperature range (14 to 122
°
F, -10 to 50
℃
).
The temperature should be measured in the air gap surrounding the inverter, shown in the
diagram above. If the temperature exceeds the allowable temperature, component life will
become shortened especially in the case of the Capacitors.
(4) Operating
Environment-Humidity
The humidity surrounding the inverter should be within the limit of the allowable percentage
range (20% to 90% / RH).
Under no circumstances should the inverter be in an environment where there is the
possibility of moisture entering the inverter.
Also avoid having the inverter mounted in a place that is exposed to the direct sunlight.
(5) Operating
Environment-Air
Install the inverter in a place free from dust, corrosive gas, explosive gas, combustible gas,
mist of coolant and sea damage.
Ensure proper spacing for ventilation to
prevent the unit from overheating.
