1. PRECAUTIONS
Use
the Inverter wlthln the allowable ambient temperature range.
The service life of the inverter depends on ambient temperature.
Ambient temperature should be as low as possible, such that the
allowable range is not exceeded. Care should be taken for installation
direction and the environment.
