Ensure Adequate Ventilation
To summarize the caution messages
– you will need to find a solid, non-flammable,
vertical surface that is in a relatively clean and dry environment. In order to ensure enough
room for air circulation around the inverter to aid in cooling, it is recommended to maintain
the specified clearance and the inverter specified in the below diagram
CAUTION: Be sure to maintain the specified clearance area around the inverter and to
provide adequate ventilation. Otherwise, the inverter may overheat and cause equipment
damage or fire.

Electrical Wiring
You will connect wiring to the input of the inverter. First, you must determine whether the
inverter model you have required three-phase power only, or single-phase power only. All
models have the same power connection terminals [R/L1], [S/L2], and [T/L3]. So you must
refer to the specifications label (on the side of the inverter) for the acceptable power
source types! For inverters that can accept single-phase power and are connected that
way, terminal [S/L2] will remain unconnected. Note the use of ring lug connectors for a
secure connection.
