3.1 Environment
Installation environment has a direct effect on the correct operation and the life expectancy of the
inverter, Install the inverter in an environment complying with the following conditions:
Protection
Protection class
IP20 / NEMA 1 & IP66 / NEMA 4X (Depending on models)
Suitable Environment
Operating
temperature
IP20 / NEMA 1 type:
–10 ~ 50℃ inside distributor (without sticker on dust cover.),
–10 ~ 40℃ outside distributor (with sticker on dust cover.).
