This section will guide you through the following basic steps of installation:

1. Study the warnings associated with mounting the inverter.
2. Select a suitable mounting location.

NOTE: If the installation is in an EU country, study the EMC installation guidelines in 
Appendix D.

3. Cover the inverter’s top ventilation openings to prevent debris from falling inside.
4. Check the inverter mounting dimensions for footprint and mounting hole locations.
5. Study the caution and warning messages associated with wiring the inverter.
6. Connect wiring for the inverter power input.
7. Connect wiring to the motor.
8. Uncover the inverter’s ventilation openings that were covered in Step 3.
9. Perform a powerup test.
10.  Make observations and check your installation.

Step 1: Study the following caution messages associated with mounting the inverter. This is the 
time when mistakes are most likely to occur that will result in expensive rework,  equipment 
damage,  or personal injury.

CAUTION: Be sure to install the unit on flame-resistant material such as a steel plate. Other-
wise, there is the danger of fire.

CAUTION: Be sure not to place any flammable materials near the inverter. Otherwise, there is 
the danger of fire.

CAUTION:  Be sure not to let the foreign matter enter vent openings in the inverter housing, 
such as wire clippings, spatter from welding, metal shavings, dust, etc. Otherwise, there is the 
danger of fire.

CAUTION:  Be sure to install the inverter in a place that can bear the weight according to the 
specifications in the text (Chapter 1, Specifications Tables). Otherwise, it may fall and cause 
injury to personnel.

CAUTION:  Be sure to install the unit on a perpendicular wall that is not subject to vibration. 
Otherwise, it may fall and cause injury to personnel.

CAUTION: Be sure not to install or operate an inverter that is damaged or has missing parts. 
Otherwise, it may cause injury to personnel.

CAUTION: Be sure to install the inverter in a well-ventilated room that does not have direct 
exposure to sunlight, a tendency for high temperature, high humidity or dew condensation, high 
levels of  dust, corrosive gas, explosive gas, inflammable gas, grinding-fluid mist, salt air, etc. 
Otherwise, there is the danger of fire.
