Post-Installation Checklist
After completing the installation, check the items in the following table to make sure that the
inverter has been safely and correctly installed.
Installation
Location/Power
I/O Verification
Is the installation location appropriate?
Does the environment meet the inverter’s operating conditions?
Does the power source match the inverter’s rated input?
Is the inverter’s rated output sufficient to supply the equipment?
(Certain circumstances will result in degraded performance.
Is a circuit breaker installed on the input side of the inverter?
Is the circuit breaker correctly rated?
Are the power source cables correctly connected to the R/S/T terminals
of the inverter?
(Caution: connecting the power source to the U/V/W terminals may
damage the inverter.)
Are the motor output cables connected in the correct phase rotation
(U/V/W)?
(Caution: motors will rotate in the reverse direction if three-phase cables
are not wired in the correct phase rotation.)
Are the cables used in the power terminal connections correctly rated?
Is the inverter grounded correctly?
Are the power terminal screws and the ground terminal screws
tightened to their specified torques?
Are the overload protection circuits installed correctly on the motors (if
multiple motors are run using one inverter)?
Is the inverter separated from the power source by a magnetic
contactor (if a braking resistor is in use)?
Are advanced-phase capacitors, surge protection, and electromagnetic
interference filters installed correctly?
(These devices MUST not be installed on the output side of the inverter.)
Are STP (shielded twisted pair) cables used for control terminal wiring?
Is the shielding of the STP wiring properly grounded?
If 3-wire operation is required, are the multi-function input terminals
