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 damage or parts missing.
2. Surface for Mounting of Inverter
The temperature of the Inverter heatsink can become very high (the highest being about 150ºC). The
surface, which you are mounting the Inverter onto, 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 a reactor.
3. Operating Environment - Ambient Temperature
The ambient temperature surrounding the Inverter should not exceed the allowable temperature range
(-10 to 40ºC). When using at 50ºC of ambient air temperature, the rated output current will be reduced.
(P.4-18)
The temperature should be measured in the air gap surrounding the Inverter, shown in the diagram
above. If the temperature exceeds the allowable temperature, the 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%). 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.
