WARNING: In the cases below involving a
1.The unbalance factor of the power supply is 3% or higher.
2.The power supply capacity is at least 10 times greater than the inverter capacity (or the power supply capacity is 500 kVA or more).
3.Abrupt power supply changes are expected, due to conditions such as:
a.Several inverters are interconnected with a short bus.
b.A thyristor converter and an inverter are interconnected with a short bus.
c.An installed phase advance capacitor opens and closes.
Where these conditions exist or when the connected equipment must be highly reliable, you MUST install an
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 C.
3.Place covers over the inverter’s ventilation openings to prevent debris from entering.
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.Remove any covers applied in Step 3 from the inverter’s ventilation openings.
CAUTION: The inverter is shipped with a plastic cover over the top vent grill. REMOVE this cover after the installation is complete. Operation with this cover in place will not allow proper cooling, and damage to the inverter may result.
9.Perform a powerup test.
10.Make observations and check your installation.
