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
(usually -10 to 50ºC).
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
(usually 5% 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.
