4.0 Environment and Installation
The environment will directly affect the proper operation and the life span of the inverter. To ensure that the inverter
will give maximum service life, please comply with the following environmental conditions:
4.1 Inverter Mounting
When mounting and installing one or more inverters on a panel or in an enclosure, ensure that the placements and
clearances are correct
. (see Fig.’s 4.1.1 and 4.1.2). Also make sure that the inverter(s) are mounted
vertically
to
maximize air flow to the heatsink. To further increase airflow, the dust cover on the inverter(s) may be removed,
provided that the environment is free from contaminants.
